Knobbly granuloma annulare (GA) of the fingers of a milkman--a possible relationship to his work.

We report a case of an unusual presentation of granuloma annulare involving the fingers of both hands. The configuration and site is probably related to the particular nature of the man's work as a milkman.

Basal-cell carcinoma of the breast--treatment with retinoids.

Retinoids have previously been described in the treatment of cutaneous malignancies and premalignancies. A case is reported of a patient with multifocal basal-cell carcinoma treated with a synthetic aromatic derivative of retinoic acid (etretinate) which resulted in complete resolution of the carcinoma confirmed by microscopy.

An XO/XX mosaic sheep with associated gonadal dysgenesis.

A female sheep with an apparent XO/XX karyotype was discovered while screening barren ewes. The animal exhibited a normal phenotype. This is the first reported case of mosaicism associated with gonadal dysgenesis in the sheep.

A composite malignant tumour of the elderly female breast.

A composite malignant tumour arising in the breast of an elderly woman is described. The cystic tumour containing areas of squamous metaplasia, bone formation, adenocarcinoma, and osteosarcoma was surrounded by the typical changes of mammary dysplasia (fibroadenosis). The classification and acceptance of such tumours is highly debatable.
