Infiltrating lipomas are unusual benign tumours of mesodermal origin which infiltrate adjacent skeletal muscle and tend to recur after excision. We report three previously unrecorded cases that developed about the mouth, and describe the clinical characteristics of these lesions, together with those of the seven previously reported cases. We have identified a number of differences from oral lipomas that could be of diagnostic value.

A skin substitute has been developed by growing a large number of epidermal cells from a skin biopsy (1 cm2) taken from burn patients. In tissue culture the cells divide and grow quickly to form a monolayer sheet. These sheets were then trypsinized into free cells, which were applied onto the wounds of two patients suffering from full skin thickness burns. The cultured epithelial grafts continued to thicken and expand successfully until they became confluent with the surrounding epidermis. All the wounds healed successfully. Clinically and histologically these cultured epithelial autografts were proven to be of the same quality as split thickness skin grafts.
Two cases of phycomycosis of the abomasum in dromedary camels are described. In one of the cases there is evidence of spread to the liver. The pathology and pathogenesis of the disease are discussed. We believe this is the first report of phycomycosis in Camelidae.
Nine patients (six females and three males), median age = 27.5 years (range 13-36) with caecal diverticulitis are presented. All underwent surgery with a suspected diagnosis of acute appendicitis. Per-operative diagnosis was possible in five cases, two cases were thought to have other benign pathology, but malignancy could not be excluded in the remaining two cases. Local excision was carried out in five cases, a right hemicolectomy was performed in the rest. Histology showed true diverticuli in eight cases, severity of the inflammation made it difficult to comment on the ninth case. Postoperative barium enema was carried out in six cases, which showed no further diverticuli in the colon. We conclude that preoperative diagnosis of caecal diverticulitis is difficult, and that true solitary caecal diverticuli present in a younger age group than the false caecal and ascending colon diverticuli and that they are probably congenital in origin.
