Mycobacterium haemophilum as the Initial Presentation of a B-Cell Lymphoma in a Liver Transplant Patient

الملخص EN

A 66-year-old woman presented with pustular lesions of her face, trunk, and limbs and an acute arthritis of the knees and elbows.

She had a complex medical background and had been on immunosuppressants for three years after a liver transplant.

Tissue samples from her skin lesions and synovial fluid showed acid-fast bacilli.

Mycobacterium haemophilum, an atypical mycobacteria, was later grown on culture.

During her treatment with combination antibiotic therapy, she developed a pronounced generalised lymphadenopathy.

Histology showed features of a diffuse B-cell lymphoma, a posttransplant lymphoproliferative disorder (PTLD).
