A Case of Trichofolliculoma in the Nasal Vestibule / 대한이비인후과학회지

Trichofolliculoma is a rare skin lesion. It is an adnexal tumor of hair follicles, which was first described by Miescher. Trichofolliculoma is a hamartomatous lesion of hair follicle origin, intermediate in differentiation between a hair follicle nevus and trichoepithelioma 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 difficult clinically and is based mainly on histopatholigic appearance. It is commonly misdiagnosed as sebaceous cyst, nevus, and basal cell carcinoma. Treatment is by simple excision and recurrence is rare. We report a case of trichofolliculoma of nasal vestibule with a review of literature.

A Case of Psammomatoid Ossifying Fibroma of Sinonasal Tract Presenting with a Facial Deformity and Choanal Atresia / 대한이비인후과학회지

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 fibroosseous lesions. Clinical manifestations vary from proptosis, nasal obstruction and headache to cosmetic disfigurement, depending on 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 deformity and choanal atresia, had a history of incomplete surgical excision. The choanal atresia was completely removed by endoscopic approach and the mass in the sinonasal tract was removed by midfacial degloving approach. We report this case with review of the literature.

A Case Report of Leiomyoma of the Hard Palate / 대한이비인후과학회지

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.
