   Abstract 

A 54-year-old man, presented with leonine facies and multiple tumours more over the exposed parts of the body. On investigation, it turned out to be a case of primary cultaneous B-cell lymphoma with a distrinctive histopathology. Chemotherapy was given with a good therapeutic response.

   Introduction Top

Cutaneous lymphomas, arising from T or B lymphocytes, constitute an uncommon but nevertheless important entity with the so called Skin Associated Lymphoid Tissue (SALT) being either the origin (primary) or the target (secondary) in the neoplastic process.[1] The primary cutaneous lymphomas, by definition, present clinically on the skin with no extracutaneous disease at the time of diagnosis or for 6 months thereafter.2 Of these, primary cutaneous lymphomas of B cell origin are less common, their incidence being one third that of their T-cell counterpart.[3] Although several classifications like Kiel, Lukes and Collins, Rappaport and Revised European and American Lymphoma (REAL)[4] classification have been used, the one proposed by the European Organisation for Research and Treatment of Cancer (EORTC)[3] is the latest and being followed widely. The follicular centre cell type described in the EORTC classification is the commonest type of primary cutaneous B cell lymphoma and shows a characteristic histopathology5 and expression of cell surface markers like CD 19, CD 20, CD 79a[1],[6] one such case is described below.


   Case Report Top

A 54-year-old man who been a road layer for 30 years presented with one year history of progressively enlarging swellings over the face, chest and forearms. Lesions were mildly photosensitive.
On examination, multiple tumour masses of firm consistency were found infiltrating the forehead and malar areas to produce a leonine appearance [Figure - 1]. Overlying skin was hyperpigmented with peu-de-orange appearance. Similar lesions were found on the neck, upper back and dorsal aspect of forearms. No significant lymphadenopathy was detected clinically.
Histopathology of involved skin showed a normal epidermis with absence of epidermotropism. A clear subepidermal cell free Grenz zone was seen in the papillary dermis. The mid and lower dermis were diffusely infiltrated by small, round lymphocytes in a bottom heavy pattern [Figure - 2]. Radiological and bone marrow aspiration studies revealed no extracutaneous pathology.
Immuno histochemical techniques for cell markers was done. A final diagnosis of primary cutaneous B cell lymphoma of follicular centre cell type was made.
Chemotherapy with use of cyclophosphamide, adriamycin, oncovin and prednisolone was started. An excellent response with near total resolution of lesions was seen [Figure - 3]. Patient is being followed up at regular intervals.

   Discussion Top

The follicular centre cell type of primary cutaneous B cell lymphoma with its classical histopathology[5] and cell markers, as seen in this case has a favourable prognosis with good therapeutic response, a fact well documented in literature.[2],[7] Interestingly, with the patient's history of life long exposure to coal tar and sunlight, and with the distribution of lesions being limited to the exposed areas of the body, the possibility of these environmental factors playing a carcinogenic role in primary cutaneous B cell lymphoma, although hitherto unreported, needs be further explored.
