Benign lichenoid keratosis is one of the most common skin lesions that develop on the faces of middle-aged women. This study aimed to find an effective treatment method for benign lichenoid keratosis. A total of 49 patients, who had a positive diagnosis during 2010-2018, were enrolled in the study. An Investigator's Global Assessment of the lesion was done using the 5-point visual analog scale to evaluate treatment efficacy. After excluding subjects who did not have a follow-up photograph, 38 subjects were given an Investigator's Global Assessment score. Combination therapy using laser and a topical agent was useful in the management of benign lichenoid keratosis on the face. Ablative laser was effective for immediate improvement of the lesion, whereas non-ablative laser was also useful and showed several benefits over ablative laser. Optimal treatment should be decided after considering the patient's preference, compliance with treatment regimen, and skin type.

Epidermolytic acanthoma represents a rare localized form of epidermolytic hyperkeratosis, which resembles warty lesions and shows a strong predilection for the genital skin of males. Here, we present an oral solitary epidermolytic acanthoma affecting a 71-year-old Caucasian man. Clinically, the lesion was white, well-circumscribed, and sessile, measuring 2 mm in diameter and located on the posterior mandibular buccal gingiva. Microscopically, pronounced hyperkeratosis and acanthosis, with formation of keratin crypts was observed. Lesional cells of the spinous and granular epithelial layers exhibited prominent intracellular vacuolar degeneration, as well as eosinophilic paranuclear and perinuclear condensations. Intracytoplasmic eosinophilic globules were also seen. No recurrences have been reported. Investigation for low- and high-risk human papillomavirus (HPV) infection failed to reveal positivity for HPV subtypes 6, 11, 16, and 18. Literature review revealed scarce reports of epidermolytic hyperkeratosis-like changes of the oral mucosa associated with malignant neoplasms and inflammatory processes. Epidermolytic acanthoma should be considered in the differential diagnosis of benign epithelial papillomatous lesions of the oral cavity.

Follicular cysts and infundibular keratinizing acanthomas are common benign cutaneous lesions in dogs. Current treatment options include surgical excision under general anaesthesia, cryotherapy, carbon dioxide laser and retinoids, each with potential disadvantages. We describe a conscious, minimally invasive, surgical excision procedure with high success rate and no complications in five dogs.

Melanoacanthoma is a rare variant of seborrheic keratosis, which is notable for dark pigmentation and fast radial growth, making it difficult to distinguish from melanoma. Histologically, it is characterized by proliferation of keratinocytes and dendritic melanocytes. The authors report a scalp lesion, fast growing, suspected by dermoscopy and confocal microscopy examination, with dendritic cells distributed throughout the lesion. Based on these findings, it was not possible to classify this lesion as clearly benign, so it was excised. Histopathologic evaluation and immunostain were consistent with melanoacanthoma.
