Intraspinal epidermoid cyst is a rare tumor. The incidence in adults is lesser than 1% and in children lesser than 3%. Epidermoid cyst is predominantly seen at the dorsal spinal level. A large percentage of epidermoid cysts are intradural extramedullary. Intramedullary epidermal cysts are rarer, with about 70 cases reported in the literature. These may be congenital or acquired with known assoc...

BACKGROUND Lumps arising in the head and neck constitute an important diagnostic category in children. As malignancy in this age group is relatively rare, lumps that are not due to inflammatory or infective causes often prove to be cysts. Correct diagnoses of the different subcutaneous lumps are often missed because of the lack of recognition or uncertainty with management. OBJECTIVES The pur...

Epidermal cyst of the skin, also referred to as epidermoid or infundibular cyst, is a common benign cystic lesion and is thought to occur from damage to the pilosebaceous units [1]. This kind of lesion is unilocular, histopathologically lined by a stratified squamous epithelium containing a granular layer, and filled with laminated and/or basket-weave keratin within the cyst, which is believed ...

Epidermal inclusion cysts are uncommon in the breast, but the consequences can be severe when these cysts occur in the breast parenchyma. Here, we report two such cases. The patient in case 1 was an 85-year-old woman with a 3-cm palpable mass in the right breast. Mammography revealed a round and smoothly outlined mass, which indicated a benign tumor, and sonography showed an irregularly shaped ...

Abstract A 1.5-year-old male Iberian lynx born in captivity presented with a 2.2 cm exophytic nodular alopecic mass at the left tarsus medial aspect, before being released into wild. The lesion had keratinised material protruding through 1.2 pore, forming cutaneous horn. Histopathology revealed cystic dermo-epidermal lined by psoriasiform hyperplasia of epithelium, thicker base cyst, together a...

Epidermal cysts are common, benign, intradermal or subcutaneous, typically asymptomatic masses, ranging from 1 to 4 cm in size. They may occur anywhere in the body, with a predilection for the face, neck, and trunk. Transformation to squamous-cell carcinoma is rare. We present a case of a 61-year-old male patient with a large, growing mass in his posterior left gluteal region. Given the concern...

Epidermal inclusion cyst of the breast is an uncommon benign lesion and it is usually located in the skin layer. We report here on two cases of ruptured epidermal inclusion cysts in the subareolar area, which is a very unusual location for these cysts and these lesions can be mistaken for breast malignancies.

Epidermal cysts are very common lesions. Here we present the unusual case of an epidermal cyst occurring between the anal sphincters, presenting as a lump in the perineum. This was successfully excised with careful dissection of the intersphincteric plane. To our knowledge this is the only case of its kind reported in the literature.
