INTRODUCTION Hepatic choristomas or ectopic livers are uncommon, and occur due to a failure of embryological liver development. They pose a risk of carcinogenesis, with transformation to hepatocellular carcinoma (HCC) being described in the literature (Arakawa et al., 1999). It is often a silent clinical finding that can occur anywhere in the body and is usually diagnosed incidentally during ab...

Choristomas are rare entities which are aggregates of microscopically normal cells or tissues in aberrant locations. They are a "heterotopic" rest of cells, as they appear as a tumor-like mass. Herein we report a case of cartilaginous choristoma in a 54-year-old male who presented with a swelling on right lower gingiva. The histopathological examination revealed features of a well circumscribed...

Intraocular lacrimal gland tissue is an extremely rare choristoma. A newborn girl was seen with a fleshy, vascular tumor arising from the peripheral iris and the anterior chamber angle. The tumor was treated with topical steroids on suspicion of a juvenile xanthogranuloma; later, it grew slightly and a secondary glaucoma developed. Histopathological examination of the resected tumor showed lacr...

Epidermal choristoma is a rare, congenital lesion in which islands of ectopic skin are found within the oral cavity. They present as pigmented macules or papules on tongue. Histologic appearances characteristic and benign. We three cases review current literature recommend observation rather than complete excision should be considered reasonable management option.
