INTRODUCTION
Cutis marmorata telangiectatica congenita (CMTC) is a rare capillary malformation characterized by persistent reticular and violaceous erythema. We present two cases of CMTC.
CLINICAL OBSERVATION
The first case involved a 13-month-old male with a reticular violaceous macule on the left gluteal region and a brownish papule with Darier's sign on the inner malleolus of the left foot, which was biopsied, revealing > 15 mast cells per field, leading to a diagnosis of CMTC and solitary cutaneous mastocytoma. The second case involved a newborn with a characteristic CMTC lesion without other malformations at birth, who subsequently developed two cutaneous tumors consistent with infantile hemangiomas during follow-up.
DISCUSSION
CMTC is a benign condition. However, approximately 50% of cases exhibit associated anomalies. When CMTC is suspected, musculoskeletal, ophthalmological, and cutaneous malformations should be ruled out. To the best of our knowledge, this is the first report of CMTC associated with mastocytoma and one of the few cases associated with infantile hemangioma.

A 63-year-old woman with light skin and a history of chronic sun damage presented with a painless, pale macule on her nasal tip. A punch biopsy was performed due to concerns about skin conditions like vitiligo or morpheaform basal cell carcinoma (BCC). The biopsy confirmed a micronodular BCC, an unusual presentation, as these typically manifest as an erythematous macule or thin papule/plaque. This report highlights the importance of considering various factors and differential diagnoses to ensure the best patient care and the need for vigilance in diagnosing rare presentations of BCC.

Syphilis is a sexually-transmitted disease with various clinical stages. Secondary syphilis manifestations may mimic other skin lesions. Patient co-infected with Human Immunodeficiency Virus (HIV), with CD4 cell counts of 200-499 cells/mm, often manifests an atypical cutaneous lesion, which may also occur as nodular or ulcerative lesions. Generalized nodulo-ulcerative lesions without systemic symptoms in secondary syphilis patients with HIV co-infection are rarely reported. A 22-year-old man presented with generalized asymptomatic multiple erythematous papules and plaques with scales, as well as nodular and nodulo-ulcerative lesions on the trunk, both arms, and both legs. His lesions spread progressively without the presence of any prodromal symptoms or adenopathy. He was previously diagnosed with HIV and is currently on antiretroviral medications, with a CD4 cell count of 388 cells/μL. His venereal disease research laboratories (VDRL) result was reactive (titer of 1:256). His hemagglutination assay (TPHA) result was also reactive (titer of 1:10,240). A skin biopsy was performed from the nodulo-ulcerative lesion on his back. Hematoxylin-eosin staining revealed a hyperplastic epidermis, a massive influx of plasma cells, and lymphocyte infiltration into the deep dermis, especially in the peri-adnexal, peri-vascular, and peri-muscular regions. The patient was diagnosed with secondary syphilis with HIV co-infection. He had no previous history of drug allergy. A single dose of 2.4 million units of benzathine penicillin G was administered. Almost all the lesions became hyperpigmented macules after two weeks and resolved completely after one month. His VDRL titer declined to 1:32 after three months. The various atypical lesions of secondary syphilis may lead to misdiagnosis and delayed treatment. The presence of multiple asymptomatic nodulo-ulcerative lesion without prodromal symptoms may indicate the presence of secondary syphilis, notably in patients co-infected with HIV. Therefore, knowledge of atypical cutaneous manifestations of secondary syphilis is warranted in order to treat patients accordingly.

Congenital dermal melanocytosis (DM) represents a common birthmark mainly found in children of Asian and darker skin phototype descent, clinically characterized by an oval blue-grey macule or macules, commonly located on the lumbosacral area. In rare DM cases, when presenting with diffuse macules persisting during the first years of life, it could represent a cutaneous feature of mucopolysaccharidoses (MPS). Extensive congenital DM is actually associated with Hurler syndrome (MPS type I) and Hunter syndrome (MPS type II), although several reports also described this association with MPS type VI and other lysosomal storage disorders (LySD), including GM1 gangliosidosis, mucolipidosis, Sandhoff disease, and Niemann-Pick disease. Here, we present the case of a two-year-old boy presenting with extensive dermal melanocytosis, generalized hypertrichosis, and chronic itch, harboring a heterozygous variant of uncertain significance, NM_152419.3: c.493C>T (p.Pro165Ser), in the exon 4 of gene, whose mutations are classically associated with MPS IIIC, also known as Sanfilippo syndrome. This is the first report that highlights the association between extensive congenital DM and MPS type IIIC, as well as a pathogenetic link between heterozygous LySD carrier status and congenital DM. We speculate that some cases of extensive congenital DM could be related to heterozygous LySD carriers, as a manifestation of a mild clinical phenotype.

INTRODUCTION
Zosteriform Lichen Planus represents a relatively uncommon variant of LP. It is characterized by a distinctive distribution following Blaschko's line and involving multiple dermatomes, setting it apart as a unique manifestation. There have been several cases of cutaneous LP reported, but relatively few of them presented as zosteriform LP. To our knowledge, this is the first documented case of zosteriform LP as an adverse drug reaction.
PRESENTATION OF CASE
A 62-year-old female presented to the dermatology clinic with asymptomatic hyperpigmented patches that exhibited gradual spreading. The patient had a history of breast cancer and underwent a mastectomy procedure, chemotherapy, adjuvant therapy, and radiation treatment. A dermatological examination revealed the presence of multiple hyperpigmented, ill-defined macules arranged linearly on the left flank and inner thigh.
DISCUSSION
A biopsy confirmed the diagnosis as Lichen Planus. The patient's condition significantly improved following a nine-week topical steroid with dose tapering.
CONCLUSION
Zosteriform LP is a rare adverse skin reaction associated with chemotherapeutic drugs. The immunosuppression induced by chemotherapy may trigger T-cell activation, leading to a lichenoid tissue reaction. A thorough patient history assessment is essential for the management of such adverse reactions.

Syphilis is a re-emerging disease, and an increasing number of cases are being reported in Italy and worldwide. In this report, we present a case of a male patient with secondary syphilis characterized by the heterogenicity of the lesions: hyperkeratosis, psoriasiform-like lesions, papules, macules, and patchy alopecia on the scalp. The patient had applied several topical antimicrobials and steroid medicaments and taken oral acyclovir, which yielded no relief, for a previous wrong diagnosis. At the time of his presentation to our clinic, syphilis was suspected and confirmed by serology. The administration of a single intramuscular dose of penicillin led to a full recovery in three weeks. Screening for HIV and other sexually transmitted infections returned negative. Clinicians should maintain a high index of suspicion for syphilis when encountering sexually active patients with atypical skin manifestations.

Gigantic melanocytosis is a rare and peculiar familial disorder of pigmentation. It presents as diffuse hyperpigmentation interspersed by raindrop-like hypopigmented macules predominantly involving the sun-exposed areas and later progressing to involve the photoprotected areas as well. All the cases described in the literature were observed to be commencing in the first year of life and were more common in males. Hereby, we report a 28-year-old female who presented with adult-onset gigantic melanocytosis with no similar familial history.

Review
INTRODUCTION
Melasma is an acquired disorder, which presents with well-demarcated, brown-colored hyperpigmented macules, commonly involving the sun-exposed areas such as the face. It is a chronic and distressing condition, affecting the patients' quality of life, and has been conventionally treated with "first-line" agents including hydroquinone (HQ) alone or as a part of a triple combination cream (TCC), while "second-line" options include chemical peels, and third line options include laser therapy.
MATERIALS AND METHODS
A systematic search was performed for all topical and systemic treatments for melasma up till May 4, 2021, using the PubMed and EMBASE databases, according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) protocol. The search terms "melasma" and "treatment" were used to search for the relevant articles on both these databases, and a total of 4020 articles were identified. After removing the duplicate entries and screening the titles, abstracts, and full-text articles, we identified 174 randomized controlled trials (RCTs) or controlled clinical trials.
RESULTS
Based on our review, HQ, TCCs, sunscreens, kojic acid (KA), and azelaic acid receive grade A recommendation. Further large-scale studies are required to clearly establish the efficacy of topical vitamin C, resorcinol, and topical tranexamic acid (TXA). Several newer topical agents may play a role only as an add-on or second-line drugs or as maintenance therapy. Oral TXA has a strong recommendation, provided there are no contraindications. Procyanidins, Polypodium leucotomos (PL), and even synbiotics may be taken as adjuncts.
DISCUSSION
Several newer topical and systemic agents with multimodal mechanisms of action have now become available, and the balance seems to be tipping in favor of these innovative modalities. However, it is worth mentioning that the choice of agent should be individualized and subject to availability in a particular country.

BACKGROUND
Granuloma annulare (GA) has diverse clinical manifestations including papules, plaques, and nodules on the extremities that are skin-colored, pink, or purple. Approximately 15% of all GA cases are considered generalized GA.
CASE SUMMARY
Herein, we describe the case of a pediatric patient who initially presented with papules and later developed generalized atrophic macules. Upon examination, two different morphologic lesions were histopathologically confirmed: Epithelioid nodular GA and scattered histiocytic infiltrative GA. This patient exhibited rare clinical manifestations that differed throughout the course of the disease. The varying histopathological types and clinical manifestations of GA may be linked to the different stages of the disease.
CONCLUSION
This rare case demonstrates the different histopathological features of different stages and clinical manifestations of granuloma annulare in an infant.
