Hailey-Hailey disease successfully treated with photodynamic therapy: Case report.

Hailey-Hailey disease (HHD) is a rare genetic benign condition resulting in blisters predominantly on the skin folds. The inheritance is autosomal dominant with complete penetrance, but a variable expressivity in affected family members. It can be triggered by a vast variety of factors such as sweating, weight gain, infection, trauma, pregnancy, and ultraviolet radiation, but the major cause of the disease is a mutation in the ATP2C1 gene. The lesions are typically distributed symmetrically within intertriginous regions such as the retroarticular folds, axillae, inguinal, and perianal regions and presents as flaccid vesicles and blisters on erythematous skin, giving rise to erosions, fissures, and vegetations. There is no specific therapy for HHD. The therapeutic approach to HHD involves the control of exacerbating factors, secondary infections, and cutaneous inflammation. Because of the rarity of the disease, evidence of efficacy for topical or systemic therapies is mainly based on small observational studies, case reports, and clinical experience. We present a case of HHD successfully treated by photodynamic therapy (PDT) with a topical liposomal chlorin photosensitizer.

Sarcoid Granulomas and Systemic Sarcoidosis Triggered by Cosmetic Tattoos.

Cosmetic tattooing of eyebrow and lips has become very popular and is expected to be paralleled by more frequent complications. We present 4 cases of granulomas in cosmetic tattoos complicated by regional or systemic manifestations of sarcoidosis including affection of the lungs in 2 cases, the activity triggered by the tattoo. Three cases of traditional decorative tattoos on extremities serve as reference. It is noteworthy that cosmetic tattoos despite small size and thereby low relative dose of pigment injected in the skin can trigger fully developed systemic sarcoidosis. It is hypothesized that iron oxide pigments popular in cosmetic tattoo inks of red or brown color may be prone to elicit sarcoid reactions and thus carry a special risk of granuloma. In decorative tattoos, carbon black is the commonest trigger. It is emphasized that the finding of granulomas in tattoos shall be followed by search of other manifestations of sarcoidosis through patient history and diagnostic examinations to exclude pulmonary, ocular, and other organ manifestations. Patients with granulomas in tattoos shall be informed that active sarcoidosis, if not already present, can become manifest later with a latency of months or years and often with abrupt debut when the triggering tattoo may be overlooked by the doctor who is unfamiliar with this less common type of sarcoidosis.

A case of polymorphic dermal angiitis in a B-cell chronic lymphocytic leukemia patient during rituximab therapy.

The aim of the study is to describe a case is of clinical interest as the first known occurrence of skin vasculitis during rituximab treatment. The article describes a case of polymorphic dermal angiitis, a combination of hemorrhagic and ulcerative-necrotic forms against the background of rituximab treatment in a 53-year-old woman suffering from chronic lymphocytic leukemia (b-CLL). During four hours after the 5th intravenous administration of rituximab, the appearance of painful rashes on the skin of both shins of a patient was observed. In the following few days, a progression of the pathological skin process was noted. The treatment with prednisolone in the amount of 50 mg/day, amoxicillin and clavulanic acid in the amount of 1000 mg twice per day and Diflucan in a dosage of 50 mg/day for 15 days was prescribed. In a local therapy, wet-drying bandages with antiseptic solutions, combined topic glucocorticosteroid preparations, drugs that improve trophic and tissue regeneration were recommended. After discharge, the patient continued to receive prednisolone in the amount of 50 mg/day for 14 days with a slow decrease in the dosage of the drug until the withdrawal under the supervision of a dermatologist. The described experience of how combined forms of polymorphic dermal angiitis are developing can be considered a result of toxic drug response to rituximab.

A rare case of Buschke-Löwenstein tumor in HPVnegative patient.

Buschke-Löwenstein tumor is known to manifest not only in sexually active people and adolescents exposed to violence or drugs, but also in people who do not have any predisposing factors or bad habits. Several studies have shown that in the majority of children with anogenital warts, HPV can be transmitted asexually by hetero- inoculation or through infected objects. To our knowledge, there are currently few reports on BLT in HPV-negative patients in the literature. In our case, the patient presented early, with multiple slow growing warts, no history of alcohol intake, drug use or smoking and no HPV infection, which makes this case unique and important.
