BACKGROUND
Visceral leishmaniasis (VL), also known as kala-azar, is caused by an intracellular parasite transmitted to humans by the bite of a sand fly, and with the source of the infection mainly being dogs. The main features of the disease are irregular fever, weight loss, hepatosplenomegaly and anaemia. Diagnosis relies mainly on bone marrow aspiration tests to find Leishman-Donovan(LD) bodies. And we report the case without febrile symptoms and hepatitis C virus antibody was probably false positive.
CASE PRESENTATION
The case was a 74-year-old male residing in Yangquan City, Shanxi Province, a VL endemic area. He presented with generalised malaise, hepatosplenomegaly and scarring pigmentation on the skin as a result of scratching. Laboratory tests showed pancytopenia, positive hepatitis C virus antibody (HCV-Ab), positive direct anti-human globulin test (DAT), positive anti-cardiolipin antibody IgG, IgM (+), and increased immunoglobulin IgG. Symptomatic treatments such as hepatoprotection and blood transfusion were given, but the patient's symptoms still persisted and his spleen and liver further enlarged. Further repeat tests were performed and found to be negative for hepatitis C virus antibodies and antigens. The patient was eventually found to be infected with by rk39 rapid diagnostic test and metagenomic next-generation sequencing(mNGS). And the patient quickly relieved after one course of treatment with sodium stibogluconate.
CONCLUSION
Patients with VL may cause abnormalities in the immune system, leading to false positives for various antibodies without clear febrile symptoms, resulting in misdiagnosis or delayed diagnosis. It is important to consider VL in cases where there is a significant hepatosplenomegaly with a relevant epidemiological history. If the diagnosis cannot be confirmed through bone marrow aspiration and the patient is not suitable for splenic aspiration, the rk39 test can be used for initial exclusion and further verified through mNGS.

A 48-year-old woman presented to the hospital with acute pulmonary embolism in the setting of presumed apixaban failure and was transitioned to heparin. Rapidly progressive pancytopenia prompted workup with suspicion for heparin-induced thrombocytopenia (HIT) as well as peripheral blood smear concerning for acute promyelocytic leukemia (APL). She was emergently started on non-heparin anticoagulation and transferred to start APL-directed treatment. Both HIT and APL were confirmed with serotonin release assay (SRA) and promyelocytic leukemia/retinoic acid receptor alpha (PML-RARA) fusion assay, respectively. We present this case to remark on the novelty of these two acute diseases occurring together. Each of these entities is a hematologic emergency requiring immediate treatment before disease confirmation. We explore the mechanisms by which HIT occurs and outline the parameters for managing APL in the acute setting. Furthermore, this case serves to examine the treatment considerations for needing to carefully balance the thrombotic and hemorrhagic risk of both HIT and APL, which are clinically well-known for coagulopathy. Fortunately, HIT in this patient recovered on anticoagulation without bleeding or worsening thrombosis. Furthermore, following induction and consolidation treatment for APL, she remained negative for residual disease.

Tuberculosis (TB), caused by the bacteria , is a highly infectious and prevalent disease. It is the leading cause of death among communicable diseases and the fifth leading cause of all diseases in India. The diagnosis can be challenging due to the disease's unique appearance and various presentations. Disseminated TB is characterized by the involvement of two or more non-contiguous sites resulting from hematogenous extension of the disease. Clinical confirmation of the diagnosis of disseminated TB is based on bacteriological or histological evidence. Based on various studies, there is evidence that satisfactory results are obtained from treatment with first-line anti-tubercular drugs. When there is a delay in diagnosis and treatment, it can become a life-threatening condition. We present a case of a 38-year-old alcoholic male who presented with generalized edema, pain, and distension of the abdomen. According to the initial presentation, the provisional diagnosis made was alcoholic liver disease, but it was later diagnosed as disseminated TB with sputum-positive pulmonary TB with abdominal involvement in the form of ascites and hepatosplenomegaly along with hematological involvement as pancytopenia. The patient started showing drastic improvement after the initiation of anti-tubercular therapy.

While Pyoderma gangrenosum (PG) is commonly associated with hematological disorders such as acute myeloid leukemia (AML), it typically presents concurrently with the hemopathy, mostly in its bullous form, among middle-aged individuals. Here, we report the unusual case of a young female patient who presented with PG in its ulcerative form, three weeks before the onset of AML. A 31-year-old female presented with a one-week history of painful perianal papulopustule that evolved into an irregular ulceration with violaceous borders, mucopurulent serosity, and erythematous surrounding skin. Laboratory work-up demonstrated elevated inflammatory markers and hyperleukocytosis, with no cytopenia, and normal peripheral blood smear. Two weeks later, the ulcer growth was noted with a similar ulceration at a venipuncture site. A complete blood count revealed pancytopenia, with 45% blasts on the peripheral blood smear. Skin biopsies showed an aseptic neutrophilic infiltrate in favor of PG. Intravenous methylprednisolone was administered with rapid resolution of the lesions. However, the patient died shortly after. The post-mortem results of bone marrow aspirate revealed AML, with immunohistochemistry of the skin lesions confirming the clonality of neutrophils derived from the leukemic clone. This case highlights a distinctive clinical presentation, illustrating the manifestation of PG three weeks before the onset of AML in its ulcerative rather than bullous form, in a young female patient.

Gaucher's disease is a rare autosomal recessive inborn error of metabolism. As the presentation of this disease is similar to more common diseases like malaria, portal hypertension, hematological disorders, and kala-azar, this rare disease may not be thought of as a differential diagnosis, and a high index of suspicion is required to avoid diagnostic delay. We report a case of type 1 Gaucher's disease in an adult male born out of a consanguineous marriage. He was from a region where the prevalence of infectious diseases and sickle cell anemia is high. He presented with abdominal distension, hepatosplenomegaly, and pancytopenia. Bone marrow biopsy showed the presence of Gaucher cells. Glucocerebrosidase levels showed decreased enzyme activity. The genetic study revealed a very rare mutation that has not been reported in the 1000 Genomes database till now. Retrospectively, the most important clue was his birth out of a consanguineous marriage of his parents.

Review
The association between Hairy Cell Leukemia (HCL) and non-tuberculous mycobacterial infections (NTMs) is well described, most notably . The exact pathophysiology is not known. We report a case of a 31-year-old male with concomitantly diagnosed HCL and disseminated infection who presented with rash, pancytopenia, and bulky axillary lymphadenopathy. The was initially diagnosed through use of cell-free DNA detection and confirmed by bone marrow and lymph node cultures. Hairy Cell Leukemia was diagnosed with peripheral flow cytometry and confirmed via the same bone marrow sample. His HCL was put into remission with a single course of cladribine and rituximab chemotherapy; however, his infection persisted for 6 months despite aggressive antimicrobial and surgical therapy. It was finally controlled using high-dose rifampin in combination with azithromycin and ethambutol. This case highlights the known link between HCL and Furthermore, it hints at potential causes beyond chemotherapy-induced immunocompromise. Notable possibilities include HCL cells acting as sanctuary sites for to evade the immune system, and subclinical infections causing NLRP3 inflammasome overactivation to trigger the oncogenic transformation to HCL. More research into the pathophysiologic link between HCL and infections would allow for more effective prevention, diagnosis, and treatment of these severe atypical infections which are the major cause of morbidity in the cladribine era of HCL treatment.

Patients with anorexia nervosa (AN) often have complications of hematologic abnormalities and pancytopenia, which can be fatal. In patients with AN, the rates of anemia, leukopenia, and thrombocytopenia have been reported as 16.7-39%, 7.9-39%, and 5-11%, respectively; in patients with severe AN, the rates of anemia, leukopenia, thrombocytopenia, and pancytopenia have been reported as 47-83%, 49.5-79%, 16.8-25%, and 16.4-23%, respectively. Hematologic abnormalities are often associated with morphological myeloid transformations such as hypoplasia, aplasia, and gelatinous marrow transformation (GMT). Hypocellularity, such as hypoplastic or aplastic, often results in a dry tap, whereas GMT does not usually result in this because of the aspiration of gelatinous material. Therefore, bone marrow aspiration in patients with pancytopenia with AN usually does not show a dry tap. The bone marrow adipocyte (BMA) volume increases in patients with AN, except in those with severe malnutrition. Patients with AN experiencing pancytopenia often exhibit GMT associated with atrophy of the originally increased volume of BMAs. Herein, we report the case of a patient with pancytopenia with AN who exhibited a dry tap on bone marrow aspiration. A bone marrow biopsy revealed sparse GMT with decreased BMA volume and areas of hematopoietic cells, adipocytes, and no GMT. A 13-year-old Japanese girl weighing 25.8 kg (BMI: 10.0 kg/m) was admitted to our hospital and received nutritional therapy. The patient presented with pancytopenia and fever, prompting the conduct of bone marrow examinations. Bone marrow aspiration resulted in a dry tap, and the bone marrow biopsy revealed sparse GMT with a decreased volume of BMAs. Additionally, an area devoid of hematopoietic cells, adipocytes, or GMT was observed. Nutritional therapy resulted in weight gain and improved pancytopenia. Upon discharge, the patient weighed 40.0 kg (BMI: 15.5 kg/m) with a normal WBC count, hemoglobin levels, and platelet count. It is significant to study hematological and bone marrow changes because patients with AN often present with hematologic abnormalities. The identification of sparse GMT, which is associated with a decrease in BMA volume and the presence of an area devoid of hematopoietic cells, adipocytes, or GMTs, is a novel finding. The improvement in pancytopenia following nutritional therapy suggests a link between myeloid transformation and malnutrition. Consequently, in patients with pancytopenia associated with AN exhibiting these bone marrow findings, nutritional therapy is necessary.

Protein-losing enteropathy associated with collagenous colitis (CC) is a rare but described entity in the adult population. However, literature regarding this in the pediatric population is scarce. Here we describe a 2-year-old female who presented with fevers, accompanied by nonbloody, watery diarrhea, and decreased oral intake. Work-up was significant for severe hypoalbuminemia at 1.5 grams per deciliter (g/dL), pancytopenia, and elevated fecal alpha-1-antitrypsin at 1.13 milligrams per grams (mg/g). Gastrointestinal mucosal evaluation was normal endoscopically; however, histology was consistent with CC. She responded to 12-week treatment with budesonide with resolution of symptoms and laboratory values. At this point, she has not had a recurrence 1 year later.

Herbal and dietary supplements (HDS) are a common etiology of drug induced liver injury and, specifically, Herbalife® supplements have been implicated. Hepatitis associated aplastic anemia (HAAA) is a rare and potentially fatal complication after acute hepatitis characterized by pancytopenia. While there have been rare cases of HDS leading to HAAA, no cases of Herbalife® induced liver injury leading to HAAA have been reported from this specific HDS. We report a unique case of severe aplastic anemia developing after sub-fulminant liver failure associated with chronic HDS use. This case illustrates the importance of warning the public about HDS as their use continues to increase. It is not only important to recognize HDS as etiology, but also for healthcare providers to carefully monitor these patients after resolution of liver injury for the development of HAAA.

Osteolytic lesions are infrequently observed in adult patients with acute myeloid leukemia (AML). This report details the case of a 66-year-old male patient who presented with myeloid sarcoma (MS), osteolytic lesion and pancytopenia. Effective treatments were delayed due to diagnostic challenges and the rapid progression of the disease. It is essential to consider AML in the differential diagnosis when faced with a patient presenting osteolytic lesions and pancytopenia.
