Sebaceous Trichofolliculoma: A case report.: Jeana Kim, Seong Beom Lee, Seok Jin Kang, Soo Il Chung, Sun Moo Kim; Korean J Pathol. 1995;29(6):794-796.

Abstract PDF: Sebaceous trichofolliculoma is a variant of trichofolliculoma which occurs in the sebaceous areas rich in follicles and is a relatively rare skin tumor. This tumor is a clinically and histologically easy tumor to recognize that is well differentiated. We examined a case of a consists of a 21-year-old female who had a pedunculated nodule on her scalp. Microscopically, the tumor was large, had a centrally located cavity lined by squamous epithelium and radially arranged sebaceous follicles connected to the cavity. No cytological atypia or recurrence after excision was found.

Trichofolliculoma in Korean Patients: A report of six cases.: Kyoung Mee Kim, Jai Kyung Ko, Anhi Lee, Chang Suck Kang, Byung Kee Kim, Seok Jin Kang; Korean J Pathol. 2000;34(11):957-960.

Abstract PDF: Trichogenic tumors are a very rare group of primary cutaneous neoplasms and a few tumors have been recognized. Trichofolliculoma is a benign, papular, organoid adnexal tumor of the skin and presents as a solitary skin-colored nodule. We report six cases of trichofolliculoma occurred in Korean patients consisting of three male and three female patients. The duration of disease was variable from 3 months to 5 years. The site of tumor was limited to the face and included eyelid in two cases, nose in two cases, cheek and posterior aspect of ear in each one case. The size of the mass varied from 4 to 8 mm in diameter. Microscopically, all the cases showed large central cystic hair follicle with numerous secondary follicular buds, producing a radiating pattern. The stroma was fibrotic and well demarcated from the adjacent dermis.

Trichofolliculoma: A case report.: Su Kyeong Yeon, Ki Hwa Yang, Seok Jin Kang, Sun Moo Kim; Korean J Pathol. 1994;28(1):79-81.

Abstract PDF: The trichofolliculoma is a rare tumor of the hair follicle occuring most often on the head and neck. We have experienced a case of 24-year-old female who had a small, dome-shaped, tan brown firm nodule on the nose. Under the clinical impression of a granuloma, an excisional biopsy of the nodule was done. Microscopically the lesion was composed of a large central cystic hair follicle with many srhall but well differenciated secondary hair follicles branching from the wall. Well developed secondary hair follicles were often grouped and were surrounded by a prominent stroma.
