Facial ulcerated nodules revealing primary cutaneous CD8-positive aggressive epidermotropic cytotoxic T-cell lymphoma

Nodules ulcérés du visage révélant un lymphome T cutané épidermotrope CD8+ cytotoxique agressif

Résumé

Background - Primary cutaneous CD8+ aggressive, epidermotropic, cytotoxic T-cell lymphoma is a rare disease with a poor prognosis. Herein we report a new case, with facial lesions, which was difficult to diagnose. Patients and methods - A 39-year-old woman was hospitalized for ulcerated nodules on the face that had been developing rapidly for 8 weeks. She had visited Djerba, Tunisia, 3 months earlier. No abnormalities were found on previous routine blood tests. Histopathological analysis of a skin biopsy had revealed non-specific lymphocytic infiltrate. Various therapies, including amoxicillin/clavulanic acid, valaciclovir, corticosteroids, colchicine and doxycycline, proved ineffective. Screening of the cutaneous sample for leishmaniasis proved positive using PCR but negative by direct examination and culture. Treatment was initiated with meglumine antimoniate. A further cutaneous biopsy revealed diffuse lymphocytic proliferation and led to a diagnosis of cutaneous CD8+ aggressive, epidermotropic, cytotoxic T-cell lymphoma. A PET scan showed multiple sites of hypermetabolism affecting the face and lymph nodes. Meglumine antimoniate was stopped and the patient experienced complete remission after chemotherapy. Conclusion - Ulcerated nodules with acute progression on acral sites are characteristic of cutaneous CD8+ aggressive, epidermotropic, cytotoxic T-cell lymphoma. In our case, the positive result of PCR screening for Leishmania that was ultimately considered a false positive was a confounding factor in the diagnostic process. Regarding therapy, aggressive treatment strategies such as multiagent chemotherapy and hematopoietic stem-cell transplantation are needed due to the rapid progression of the lymphoma.
