Trichofolliculoma is a rare skin lesion. It is an adnexal tumor of hair follicles, which was first described by Miescher. Trichofo-lliculoma is a hamartomatous lesion of hair follicle origin, intermediate in diferentiation between a hair follicle nevus and tri-choepithelioma as classified by Kligman and Pinkus. It usually manifests clinically as a small, slowly growing, well-demarcated, flesh-colored papule on head and neck. The diagnosis is dificult clinically and is based mainly on histopatholigic appearance. It is comonly misdiagnosed as sebaceous cyst, nevus, and basal cell carcinoma. Treatment is by simple excision and recurrence is rare. sal vestibule with a review of literature. (Korean J Otolaryngol 2007 ;50 :265-7)
Leiomyoma is a benign smooth muscle tumor that can be classified into three types:solid, vascular and ephithelioid leiomyoma. This disease occurs most frequently in the uterus, gastrointestinal tract and skin. The oral cavity is an unusual site for a leiomyoma and occurrence in the hard palate is very rare because there is so little smooth muscle tissue present in this region. Clinically, oral leiomyomas usually grow slowly and are asymptomatic firm superficial nodule like lesions, although occasional tumors can be painful. The diagnosis and treatment of oral leiomyoma is possible with complete surgical excision and histological studies by special specific stains. Recently, we experienced a 60-year-old man with 6 month history of soft mass on the hard palate. He underwent surgical resection. Pathological analysis confirmed vascular leiomyoma. Here, we report this case with review of literature.
The psammomatoid ossifying fibroma consisted of numerous cellular fibrous stroma, various bony trabeculae and calcified spherules(psammoma bodies) is known to typically involve the sinonasal tract. It is more destructive than the other benign fibroosseouslesions. Clinical manifestations vary from proptosis, nasal obstruction and headache to cosmetic disfigurement, dependingon the location and the size of lesion. Complete surgical excision is the treatment of choice because of its tendency to recur.The author recently experienced a psammomatoid ossifying fibroma of sinonasal tract in a 37-year-old male with a facial deformityand choanal atresia, had a history of incomplete surgical excision. The choanal atresia was completely removed by endoscopicapproach and the mass in the sinonasal tract was removed by midfacial degloving approach. We report this case withreview of the literature.
