Nail psoriasis has variable prevalence and heterogeneous aspects. Many of them could mimic onychomycosis (OM). It has been suggested that patients with nail psoriasis are at high risk of OM. The aim of our study was to determine the epidemiological and clinical characteristics of nail psoriasis and to estimate the frequency and the factors associated with OM in psoriatic patients. The studied group included 163 patients with psoriasis aged 18 years or older. Epidemiological and clinical data, as well as the severity of skin and nails disease by evaluating the Psoriasis Area Severity Index (PASI) and Nail Area Psoriasis Severity Index (NAPSI) scores were specified. Mycological testing was performed for patients with nail alterations. Nail involvement was found in 71.2% of patients. The most common nail alterations were subungual hyperkeratosis and onycholysis. The mean NAPSI score was 11.6. Mycological testing was performed in 104 patients with onychodystrophy. OM was diagnosed in 53% of the cases. Dermatophytes were the most isolated pathogens. OM was associated with male gender, but not with age, NAPSI, or PASI score. Psoriasis is one of the dermatoses that most commonly affect the nail. Available data about the association between nail psoriasis and OM are controversial. However, mycological testing should be routinely performed on psoriatic nails.

Pilomatrixoma is benign skin tumor that originates from the pilosebaceous follicle. In most cases it presents as a solitary asymptomatic and a firm subcutaneous nodule on the head, neck or upper extremities. Herein, we report a case of 27-year-old patient who presented with a history of multiple tumors of the upper back, the left arm, the forearms, the proximal third of the right thigh and the scalp. The biopsy showed a benign tumoral proliferation on the dermis and hypodermis with a transepidermal elimination of shadow cells islands on the perforated lesion. Pilomatrixoma is an adnexal skin tumor which may be difficult to diagnose due to different clinical and cytological findings. This diagnosis must be evoked in every patient presenting with a firm subcutaneous tumor of the head, neck or upper extremities. The histological examination confirms the diagnosis and the treatment is surgical excision.

Lichen planus (LP) is an inflammatory skin condition characterized by the presence of pruritic, polygonal, purple flattopped papules and plaques typically symmetrically distributed. The occurrence of these lesions could be attributed to the isomorphic response of koebner occuring regularly in LP. A 38-year-old woman developed pruritic purplish papules spread on a brown lichenoid patch over the left chest area 3 months after radiation therapy for an invasive carcinoma of the left breast. These lesions were confined to the radiation therapy site. Almost any type of irritant can provoke the isomorphic response including traumatisms, friction, infection and ultraviolet light. Only few cases of LP confined to radiation site have been described so far.
