A rare case of melanotic malignant trichoblastoma

Folliculosebaceous neoplasms: A review of clinical and histological features

“…Histological variants have been described, in large part dependent on varying proportions of mesenchymal and epithelial components. Rippled pattern, pigmented, clear‐cell variants and sebaceous differentiation have been reported . Like with TEP, misdiagnosis of BCC may occur.…”

“…Rippled pattern, pigmented, clear-cell variants and sebaceous differentiation have been reported. [33][34][35][36] Like with TEP, misdiagnosis of BCC may occur. Clinical data, lack of peritumoral clefting and identification of PMB help to differentiate these entities.…”

Disseminated trichoblastomas – successfull treatment with CO2 laser

“…1 First described by Headington in 1970, these tumours have been initially separated into trichoblastic fibromas, trichogenic trichoblastomas and trichogenic myxomas, in respect to the content of epithelial and mesenchymal components in them. 2 The recently used term 'trichoblastoma' was inculcated in 1993 by Ackerman et al, as a summarized concept of all benign cutaneous neoplasms, composited mostly by follicular germinative cells. 3 TB can occur at any age, but it is more commonly seen in adults, as no dominated gender distribution is usually associated.…”

“…4,5 However, it should be considered in the differential diagnostic plan, in respect to its aggressive course and specific management. 2,5 We present a 31-year-old patient who was consulted on an occasion of multiple tumour-like lesions, scattered on his back, chest, as well as in the retro-auricular area, with unspecified duration. A progressive growing of the lesions with initial symptoms of moderate pain was obtained by the patient since a couple of years ago.…”

“…7 Mohs micrographic surgery could be also considered, as the results are usually more satisfactory aesthetically. 2 Trichoblastomas may be also excised for cosmetic reasons, or if they occur in functionally sensitive areas and inflict functional disorders. 2,3…”
