BACKGROUND Pilomatrixoma , also known as Malherbes's calcifying epithelioma, known to occur in children, is not common especially in middle aged and those below 10 years of age . Pilomatrixoma presents as a firm skin nodule on eye lid or eye brow, so should be considered in the differential diagnosis of such lesions involving eyelids. CASE A 45-year-old male presented with a swelling in the l...

Calcifying epithelial odontogenic tumor is a rare odontogenic neoplasm. Its occurrence in the maxillary sinus is very rare. Maxillary tumors tend to be locally aggressive and may rapidly involve the surrounding vital structures.  We report a case of calcifying epithelial odontogenic tumor involving maxillary sinus in a 48 years old female patient with the oral mucosal involvement. The purpose o...

This report describes two cases of sebaceous epithelioma and its immunohistochemical characterization with CK 14, CK18, p63, Ki67 and Bcl-2 immunostaining. Case 1 was a 12-year-old, intact English Cocker spaniel female presenting with multiple skin nodules over one year. Case 2 was a 7-year-old, spayed poodle female with a five-month history of solitary mass. Hematoxylin and eosin (H&E) stainin...

We report a rare case of sebaceous epithelioma(SE) in the external auditory meatus of an 84-year-old woman. The tumor, measuring 1.5 cm in diameter, was hemispherical, yellowish-brown, elastic and hard. It was removed surgically without complications and there has been no recurrence two years postoperatively. The histopathologic findings were characteristic of a sebaceous epithelioma. The contr...

mann (Ewing, 1928) contends that since all epithelial tumours arise from the basal cells the term basal-cell carcinoma was not quite suitable. But Krompecher's choice of term may be justified on the ground that basal-cell epithelioma is composed of basal cells which retain their morphological characters throughout their existence, in contrast to the squamous-cell carcinoma in which the basal ce...

Two years and three months ago she first noticed a small, hard tumor near the first bicuspid tooth on the left side of the lower jaw bone. It grew slowly. In childhood there was nothing unusual about her teeth, which were perfectly regular and even up to the time of her present illness. Ex...
