Multiple recurrence of trichilemmal carcinoma of the scalp in a young adult

Trichilemmal Carcinoma of the Scalp in a Young Female: A Case Report

Trichilemmal carcinoma (TC) is a rare malignant cutaneous adnexal neoplasm originating from the outer root sheath of hair follicles, which occurs commonly in sun-exposed areas of the elderly. Here, we introduce a case of a 24-year-old woman with TC on her scalp.

Malignant tumor of outer root sheath epithelium, trichilemmal carcinoma. Clinical presentations, treatments and outcomes

OBJECTIVES

To emphasize different clinical features of tumor that can be misdiagnosed clinically.

METHODS

A total of 8 cases operated between September 2009 and 2016 at the Celal Bayar University, Faculty of Medicine were included in the study. Patients' clinicopathological features, type of surgery and follow up information were evaluated. Results: Six patients were male. The average age was 75.50. The lesions were located on the head and neck, and chest wall. Six patients had a history of the rapid growth of lesion. There was no metastasis at the time of diagnosis. None of the patients needed adjuvant therapy. Mean follow up time was 19.37 months. None of the patients developed recurrence or metastasis. Conclusion: This tumor resembles basal or squamous cell carcinoma. The histopathological evaluation may lead to misdiagnosis. Regional or distant metastasis is very rare. There is no consensus about adjuvant therapy. Screening for metastasis and close follow up are mandatory.

Trichilemmal carcinoma: an unusual presentation of a rare cutaneous lesion

Trichilemmal carcinoma (TC) is a rare cutaneous neoplasm which is derived from adnexal keratinocytes, is histologically invasive, contains cytologically atypical clear cell neoplasm and is in continuity with the epidermis and/or follicular epithelium. However, the diagnostic criteria and even the existence of TC have been contentious. We report the case of a 92-year-old woman with TC of the head and neck region who presented with an unusually long history. She was treated successfully with wide local excision. Important aspects in presentation, differential diagnosis, including histopathological features and management are discussed.

Recurrent proliferating trichilemmal tumor of the vulva: a case report

Proliferating trichilemmal tumor (PTT) is a rare but morphologically distinct tumor that usually arises on the scalp of elderly women. It is composed of multiple cysts consisting of squamous epithelium with trichilemmal keratinization without granular layer interposition. Vulvar proliferating trichilemmal cyst is very rare, with, to the best of our knowledge, only 3 cases previously reported in the literature. We describe a 39-year-old woman with recurrent PTT on the left labium majus of the vulva, which had been excised from the same side 5 years before. She had a palpable nodule, approximately 2 cm in size, which was firm, mobile, and nontender; without erythema and ulceration; and covered by normal skin on the vulva. There was no inguinal lymphadenopathy. The lesion was removed by wide surgical excision; because of the tissue elasticity, primary closure was possible. The pathology result was reported as proliferating trichilemmal carcinoma with tumor-free margins. Although local recurrence after wide excision is rare, we recommend complete excision for treatment of PTT and long-term follow-up because of the possibility of recurrence.
