‘Scarless’ removal of forehead lipomas

Congenital infiltrative lipomas and retroperitoneal perirenal lipomas in a calf.

BACKGROUND Congenital lipocytic tumours have rarely been reported in cattle. Lipomas are benign tumours, but infiltrative lipomas have significant health implications due to their aggressive infiltrative growth pattern. CASE PRESENTATION A calf was born with skeletal malformations and soft tissue proliferations, primarily on the external thoracic wall. The calf was euthanized for welfare reas...

Lipomas of corpus callosum

Intracranial lipomas (iLp) are very rare congenital malformative lesions, being less than 0.1% of intracranial tumors [1]. They originate from abnormal differentiation of the mesenchimal tissue of meninx primitiva [2–4]. Intracranial lipomas mainly localize in the pericallosal zone, where they are mostly asymptomatic, being frequently associated to other defects of differentiation of the midlin...

Two ileocecal valve lipomas

A 68-year-old woman presented with a 4-year unexplained intermittent abdominal pain recently complicated with rapidly transient obstruction episodes. Physical examination, plain radiograph and ultrasound of the abdomen were normal. At colonoscopy, a submucosal tumor (Fig. 1A) 0.5 cm in diameter prolapsing through the ileocecal valve was found. On removal of the tumor, after endoloop placement, ...

Cytogenetic profile of 109 lipomas.

Cytogenetic analysis of short-term cultures was carried out on 109 lipomas from 92 patients. Clonal chromosomal abnormalities were present in 50% of the tumors analyzed. Based on the results, three main cytogenetic groups were identified and included: (a) tumors with normal karyotypes, (b) tumors with abnormalities involving region q13-15 on chromosome 12, and (c) tumors with other clonal aberr...
