introduction: epidermoid tumors comprise 1% of intracranial tumors. although reported, intraosseous epidermoid tumors are even more rare. cystic lesions of the petrous apex are uncommon and surgically challenging; the most rare pathology is presumed to be epidermoid.rncase presentation: this is a case of a 61-year-old woman with a large skull-base tumor extending inferiorly from the c1-c2 artic...

introduction: epidermoid cysts are rare, slow‑growing, benign, developmental cysts, which are derived from abnormally situated ectodermal tissue. epidermoid cysts of the floor of the mouth represent <0.01% of all oral cysts. so far, only a few cases have been reported. case report: hereby, we present a case of a giant sublingual epidermoid cyst, which was completely asymptomatic upon presentati...

Epidermal cyst is a benign tumor that grows slowly and develops from entrapment of epidermis into the dermis. Inguinal canal is an extremely unusual location for an epidermal cyst in children. Here in, a 6-year-old girl presenting with inguinal mass which was diagnosed to be epidermal cyst in the patent processus vaginalis sac is reported. To the best of our knowledge, it is the first case of e...

An epidermal cyst is a common benign subcutaneous tumor and rarely develops malignancy. We report a case of an undifferentiated cutaneous squamous cell carcinoma (SCC) that arose from an epidermal cyst on the left side of the neck. The epidermal cyst had rapidly increased in size and presented cauliflower-like tumor. Histological study revealed undifferentiated squamous cell carcinoma that was ...

A 62-year-old male developed a solitary asymptomatic nodule on the lateral aspect of the distal interphalangeal joint of the right great toe. Histopathologic findings demonstrated a myxoid cyst with a concomitant epidermal inclusion cyst. To the best of our knowledge, this is the first case of concurrent occurrence of digital myxoid cyst and epidermal inclusion cyst. Although the exact mechanis...

conclusions the her3 expression in developmental odontogenic cysts was higher than that in inflammatory odontogenic cysts. the higher rate of her3 expression in okc may justify inherent growth potential, stimulation-independent proliferation capability, invasive growth and high recurrence rate of the cyst accepted today as a tumor. results the her3 expression had positive results in 52.4% of ok...

INTRODUCTlON Although malignancy developing in an epidermal cyst has been described,' the rarity of such an occurrence has been emphasised.2 73 34 A review of the English literature also revealed that metastatic disease in a malignant epidermal cyst has not been described. This paper reports a malignant epidermal cyst with metastatic disease and considers features which may be relevant t o its ...

A 44-year-old male patient who had undergone augmentation penoplasty 20 years previously presented with a slowly growing penoscrotal mass. The penile mass was excised totally and the pathologic diagnosis was an epidermal cyst. Epidermal cysts are benign disorders that can occur in any part of the body. However, an epidermal cyst as a late complication of augmentation penoplasty is extremely rar...
