I would like to clarify a misconception about the origin and content of dermoid vs epidermoid cysts. Reference was made to this in the article "Temporoparietal Dermoid Cysts with Intracranial Extension" by Currarino and Rutledge [1]. Although these authors ' findings of dermoid cyst with sinus in an unexpected location are certainly of interest, I must differ with the statement that inclusion o...

Sebaceous gland carcinoma is a rare fast growing cutaneous cancer. It is derived from the adenxal epithelium of sebaceous glands. Sebaceous carcinomas are generally divided into those occurring in periocular or extraocular locations. Ocular sebaceous carcinomas occur most commonly in upper eye lid, in the elderly with a predilection for females and Asian populations. Due to its clinical resembl...

Extraocular sebaceous carcinoma is a relatively rare skin appendage carcinoma [1]. Although ocular sebaceous carcinoma is thought to arise from the Meibomian glands and glands of Zeis, there is no evidence that extraocular sebaceous carcinoma arises from pre-existing sebaceous glands [2]. Most sebaceous carcinomas are invasive [1], however, only a few cases of sebaceous carcinoma associated wit...

Sebaceous carcinoma is a malign tumor of sebaceous glands and it is usually found on the eyelid. However, sebaceous carcinoma can arise anywhere in the body where sebaceous glands exist. Extraocular localization of the sebaceous carcinoma is rare and accounts for 25% of all cases. Sebaceous carcinoma is more common in women between the ages of 60 and 70. Moreover, Asian population is more likel...

INTRODUCTION This case illustrates the unusual complication of granulomatous peritonitis following rupture of a dermoid cyst in pregnancy resembling disseminated ovarian carcinoma. To the best of the authors' knowledge, this is the first report of this complication during advanced pregnancy in the literature. CASE PRESENTATION A dermoid cyst ruptured during surgical removal in the second trim...

BACKGROUND Sebaceous glands contribute significantly to the barrier functions of the skin. However, little is known about their homeostasis and tumorigenesis. Recently, increased expression of stem cell marker Lrig1 has been reported in sebaceous carcinoma-like tumors of K14ΔNLef1 transgenic mice. In this study, we analyzed the Lrig1 expression in human sebaceous tumors. METHODS Twenty-eight ...

Mature cystic teratoma (MCT) is the most common type of ovarian germ cell tumor occurring in females of reproductive age. It is typically benign, but rare malignant transformations have been reported in 1-2% of the cases. Among a wide variety of malignancies arising in MCTs, high grade lymphomas are the least common. We present a case of a 45- years -old female with a unilateral adnexal ma...
