An interesting case of plasmacytoma of the scalp is described. Extramedullary plasmocytoma of scalp is rarely reported. This patient was treated with external radiotherapy dose of which was 40 Gy/20 fraction. Disease responded very well to radiotherapy.

  ::   IntroductionTop

Extramedullary solitary plasmacytoma is an uncommon presentation[1]. Plasmacytoma of skin and subcutaneous tissue is a rare tumour. Only a few cases have been reported in the literature so far[2],[3].

  ::   Case reportTop

A 55-year-old female reported at the Gujarat Cancer & Research Institute. She complained of a gradually increasing swelling over frontoparietal region of head of 6 months duration [Figure:1]. On examination a rounded swelling of 8 x 10 cm size was palpable over frontoparietal region. It was nontender and firm in consistency with restricted mobility. No lymphadenopathy or organomegaly was noted.

On investigations, Xray skull showed erosion of outer table of frontal bone. Radiological skeletal survey was normal. Bence Jones proteins were negative in urine. Bone marrow examination showed no evidence of infiltration by plasma cells. Histopathological examination of punch biopsy obtained from the swelling revealed it to be plasmacytoma.

Local radiotherapy was given over the swelling by two tangential portals. A total tumour dose of 40 Gy was delivered in 20 fractions. There was a significant (> 50%) regression of the swelling at the end of radiation treatment. Patient was then referred for chemotherapy.

  ::   DiscussionTop

Extramedullary plasmacytoma is uncommon. In head and neck region, their frequency is about 0.5%. The tumour shows intense infiltration by plasma cells on histopathological examination[1].

The tumour is radiosensitive and responds to local radiotherapy[4]. Most of the patients subsequently develop the features of multiple myeloma.

Plasmacytoma of skin were reported in a series of 8 cases by Torne et al[2]. Subcutaneous plasmacytoma of breast region has also been reported [3] Plasmacytoma of scalp is probably the rarest occurrence. In this case, the tumour was subcutaneous in origin and was eroding the frontal bone.
