Deskripsi
Primary Cutaneous Diffuse Large B Cell Lymphoma, Leg Type (PCDLBCL, LT) comprises 4% of all cutaneous lymphomas, and it presents as an aggressive form of lymphoma. Rarely do pathologist/cytologists find specimens of PCDLBCL, LT on Fine Needle Aspiration Cytology (FNAC). The mimickers on FNAC are metastatic small cell carcinoma, Merkel Cell Carcinoma (MCC), Malignant Melanoma (MM), Cutaneous Alveolar Rhabdomyosarcoma and Primary Cutaneous Ewing's Sarcoma (PCES). A 75-year-old female patient presented in the Department of Surgery with multiple nodules on the leg for three months. On cytology small round cell tumour with possibility of non hodgkin lymphoma was given and biopsy was advised. The confirmation of PCDLBCL, LT on cytology is not recommended however, it is emphasised that it can be picked up on FNAC and distinguished from its mimickers. Because of the aggressive nature and poor prognosis with the frequent relapses and tendency for extracutaneous spread, it is considered to be a distinct type of cutaneous lymphoma which needs to be diagnosed and treated as early as possible.
