Pseudolymphoma, also known as Jessner’s lymphocytic infiltration, is a benign but usually chronic, T-cell infiltrating disease with erythematous papules and plaques usually seen on the skin of the face, neck, and back. The use of leech therapy also known as hirudotherapy has increased in recent years. Here, we report a 52-year-old male patient who had undergone hirudotherapy in his neck and developed infiltrating plaques after four months. A skin biopsy confirmed the diagnosis of Jessner’s lymphocytic infiltration. In parallel with the increasing use of hirudotherapy in recent years, the side-effect reports will likely to increase. Indications and contraindications of hirudotherapy, which is being used officially in hospitals, should be taken into consideration.

Review
Hepatic pseudolymphoma is a rare and controversial condition, the clinicopathological characteristics of which have not been well documented. In this study, we retrospectively examined clinical and pathological features of five patients (two males and three females, 40-81 years old) with hepatic pseudolymphoma. Two patients had multiple lesions (two lesions each). Three patients had histories of chronic liver disorders, including primary biliary cirrhosis, nonalcoholic steatohepatitis, and chronic viral hepatitis B. Tumor sizes ranged from 0.5 to 5.5 cm in diameter (average, 2.1 cm). Histologically, hepatic pseudolymphoma consisted of tumorous infiltrates of mature lymphocytes with multiple lymph follicles or clusters of epithelioid histiocytes. Lymphocytes characteristically extended into nearby portal tracts. Ductal structures positive for cytokeratin 7 were entrapped in the peripheral parts of nodules. In situ hybridization of immunoglobulin light chains revealed B lymphocytes and plasma cells to be polyclonal. In addition, clonal rearrangements of immunoglobulin heavy chains could not be shown in any cases using PCR. Two patients were diagnosed by needle biopsy. Interestingly, their nodules spontaneously diminished in size without any treatment. Malignant transformation was not observed in any cases during the follow-up periods. In conclusion, this study revealed that hepatic pseudolymphoma had benign behavior. The diagnosis of hepatic pseudolymphoma can be challenging especially with biopsied specimens, but could be aided by a characteristic growth pattern, in situ hybridization, analyses of gene rearrangements, or a follow-up based on images.

Review
Actinic reticuloid (AR) or chronic actinic dermatitis is considered a sunlight-induced pseudolymphoma (PSL) on light exposed areas of the skin, which primarily affects elderly males. The disease is a severe, chronic photosensitive dermatosis, first described by Ive et al. in 1969. PSL is a group of non-cancerous lymphocytic skin disorders that simulate malignant lymphomas, but the changes usually spontaneously regress. The clinical appearance of Actinic reticuloid is variable, usually characterized by an eczematous, pruritic eruption, predominantly present on the head and neck, or other sun exposed areas, but can involve any area of the body. Thereby, crucial characteristic is photosensitivity, where at action spectrum involves UVB, UVA and visible light beyond 400 nm. The disease is considered as PSL which histologically resembles lymphoma with immunohistochemical analysis of the cutaneous infiltrate revealing presence of activated T cells, numerous histiocytes, macrophages and B cells. Moreover, the development of malignant (non-cutaneous) T cell lymphoma in the course of AR has been reported. As the disease has chronic character, it requires significant changes in the patient's lifestyle and avoidance of provoking factors such as contact allergens or sources of intense light. Thus AR should be considered in every patient who presents with persistent, unclear, erythematous skin changes on the face and neck that are related to sun exposure.

Review
We report a case of hepatic pseudolymphoma in a 67-year-old woman that was detected during an abdominal sonography screening. The lesion was further evaluated using CT, MRI, angiography, and contrast-enhanced sonography. The imaging features of this tumor are discussed herein. The diagnosis of pseudolymphoma was achieved via sonographically guided biopsy. The lesion regressed completely within 1 year.
