Plasmoacanthoma is an extremely rare verrucous tumor located on periorificial regions characterized by dense dermal plasmacytic infiltrates. Some authors classify it as a form of reactive plasma cell proliferation which represents a heterogeneous spectrum of mucocutaneous disorders. These plasma cell proliferations have been considered to be a benign immunologic inflammatory reaction to known or unknown stimuli. However, the etiology of plasmoacanthoma remains highly speculative. We report the case of a 40-year-old woman who presented with a lobulated warty lesion affecting the lower lip. Biopsy from the lesion was compatible with plasmoacanthoma, which remains an underreported disease in the dermatology literature.

Reflectance confocal microscopy (RCM) is an FDA approved noninvasive optical imaging technique that acquires cellular level-resolution skin images in vivo. Herein, we report a case of histopathologically proven large cell acanthoma (LCA) whose RCM features simulate those of squamous cell carcinoma in situ.

Epidermolytic hyperkeratosis is a histological reaction pattern seen in a variety of disease processes, including epidermolytic ichthyosis, Vorner's epidermolytic palmoplantar keratoderma, epidermal nevus, and solitary epidermolytic acanthoma. Here we present the case of a 59-year-old woman with multiple asymptomatic papules on her vulva. Clinical differential diagnoses included condyloma acuminata, seborrheic keratoses, bowenoid papulosis, adnexal tumors, and papular acantholytic dyskeratosis. Shave biopsy revealed findings consistent with epidermolytic hyperkeratosis. This case represents an interesting presentation of focally disseminated vulvar epidermolytic acanthomas and highlights the importance of a biopsy in establishing this diagnosis.

Pilar sheath acanthoma is a rare, benign follicular hamartoma. Mehregan and Brownstein fist reported this solitary, asymptomatic, and skin-colored nodule with a central pore-like opening in 1978. The classic location for these lesions is the upper lip of elderly patients. Here we report an interesting case of a pilar sheath acanthoma presenting on the left eyebrow in a middle-aged female. To our knowledge, this is the first reported case of a pilar sheath acanthoma in such a unique location.

Review
Benign follicular tumors comprise a large and heterogeneous group of neoplasms that share a common histogenesis and display morphological features resembling one or several portions of the normal hair follicle, or recapitulate part of its embryological development. Most cases present it as clinically nondescript single lesions and essentially of dermatological relevance. Occasionally, however, these lesions be multiple and represent a cutaneous marker of complex syndromes associated with an increased risk of visceral neoplasms. In this article, the authors present the microscopic structure of the normal hair follicle as a basis to understand the type and level of differentiation of the various follicular tumors. The main clinicopathological features and differential diagnosis of benign follicular tumors are then discussed, including dilated pore of Winer, pilar sheath acanthoma, trichoadenoma, trichilemmoma, infundibuloma, proliferating trichilemmal cyst/tumor, trichoblastoma and its variants, pilomatricoma, trichodiscoma/fibrofolliculoma, neurofollicular hamartoma and trichofolliculoma. In addition, the main syndromes presenting with multiple follicular tumors are also discussed, namely Cowden, Birt-Hogg-Dubé, Rombo and Bazex-Dupré-Christol syndromes, as well as multiple tumors of follicular infundibulum (infundibulomatosis) and multiple trichoepitheliomas. Although the diagnosis of follicular tumors relies on histological examination, we highlight the importance of their knowledge for the clinician, especially when in presence of patients with multiple lesions that may be the cutaneous marker of a cancer-prone syndrome. The dermatologist is therefore in a privileged position to recognize these lesions, which is extremely important to provide further propedeutic, appropriate referral and genetic counseling for these patients.
