“…Classically, patient reports a slow evolution of a nodule which would grow up rapidly to 25 cm in diameter after trauma and could become painful and ulcer [7]. This latter, although present only in our patient with malignant PTC, does not appear to be a sign of malignancy since it has been described in several benign PTC [8,9].…”

“…Histological study confirms characteristic trichilemmale keratinization. It would also appreciate architectural and cytological disorders that would differentiate simple trichilemmale cyst and PTC, although this distinction is not always obvious, especially in the early stages [7]. Histological findings could be confusing with squamous cell carcinoma (SCC); main clinical and histological differential diagnosis; especially of malignant PTC.…”

Background: Proliferating trichilemmal cyst (PTC) is a rare adnexal tumor, primarily sitting on the scalp of elderly women. Its evolution is generally benign despite the rare malignant cases described. We report a series of 9 cases of which one is malignant and metastatic. Material and methods: We retrospectively reviewed data of all patients with PTC seen at department of dermatology in the Meknes military hospital, between January 2013 and December 2017. Results: 9 cases of PTC were diagnosed, which 8 in elderly women, with 62 years mean age. Trauma was found in one third of cases correlated with rapid growth of the tumor. The latter was symptomatic in 2/3 of the cases. Ulceration involved only the malignant case. The size varied from 1,5 to 12 cm. Recurrence after surgery was noted in 2 cases (malignant tumor and multi-cystic tumor). Discussion: PTC appears to have a well-distinguished profile of the simple trichilemmal cyst. Some clinical and histological features may constitute prognostic factors of aggressiveness. Histological and immunohistochemical study is crucial in the management. A large excision remains the only guarantee of complete remission without recurrence or metastasis. Conclusion: PTC remains misdiagnosed and very few series are reported. Prospective studies would allow the identification of prognostic factors of malignancy as well as better management.

“…Wilson-Jones first described PTT in 1966 as an entity that can clinically and histologically simulate squamous cell carcinoma. 20 Initially classified as a pseudoepitheliomatous hyperplasia, a number of other terms such as proliferating epidermoid cyst, pilar tumor of the scalp, proliferating trichilemmal cyst, proliferating epidermoid cyst, giant hair matrix tumor, hydatidiform keratinous cyst, and invasive hair matrix tumor have been used [10]. PTT typically presents as a solitary, painless nodule, ranging in size from 1 to 10 cm.…”

Proliferating Trichilemmal Tumor Presenting as a Scrotal Mass in a Middle-Aged Male: An Uncommon Location

Scrotal masses encompass a heterogenous group of conditions affecting the skin and soft tissue of the scrotum or underlying testis, ranging from benign to malignant and from indolent to conditions requiring urgent medical evaluation.Accurate and timely diagnosis is imperative with scrotal masses, as the medical ramifications of different diagnoses vary widely, and the social and psychological implications can be significant. Here we present the first reported case of a middle-aged male with an enlarging scrotal/extra-testicular mass, which upon excision, was found to be consistent with a proliferating trichilemmal tumor, a benign neoplasm derived from outer root sheath of the hair follicle which has a strong capacity to simulate squamous cell carcinoma. Distinguishing between these two entities is of utmost importance due to their significantly different prognostic and treatment ramifications, and ultimately directs appropriate management of these patients.
