Aggressive infantile fibromatosis

An 8-month-old infant presented with 2 ulcerated indurated plaques in the right lower limb. The lesions grew rapidly initially but for the last 2 months, they have been stationary. Biopsy showed proliferation of fusiform fibroblasts some of which were arranged in whorls. The clinical picture and the histopathology suggested the diagnosis of an aggressive infantile fibromatosis. This is one of the types of juvenile fibromatoses, a group of tumours characterised by fibrous tissue proliferation present at birth or acquired early in childhood.

Tuberous sclerosis

Although tuberous sclerosis has been described with a diagnostic triad, it is not present consistently in all cases. Variety of skin manifestations were reported in tuberous sclerosis. This studay was undertaken to assess the frequency of various skin changes in tuberous sclerosis. Ten consecutive cases of tuberous sclerosis were studied. Angiofibroma was the commonest cutaneous manifestation. Atypical fibroxanthoma, dermatofibroma and neurofibroma were also noticed as interesting associations.

Effect of ovine luteinizing hormone and prolactin on progesterone secretion by goat granulose cells in culture

Effects of LH and prolactin on cultures of granulosa cells from the goat were analysed in terms of the secretion of progesterone. The cultures were maintained for 120 h during which time they were treated at 24 and 72 h after explantation with LH and prolactin. Progesterone secreted in the culture medium was determined by radioimmunoassay. The secretion of progesterone by the cultures in response to LH and prolactin was significantly increased (P less than 0.01) compared with that by control cultures. The pattern of steroid secretion in the two cases (LH-treated and prolactin-treated cultures) was, however, different. The secretion dropped appreciably when the concentration of hormones was increased to 100 mu./ml.
