Inflammation of Actinic Keratoses Induced by Combination of Carboplatin and Paclitaxel: Two Case Reports

The observations of a beneficial effect of 5-fluorouracil-induced actinic keratoses (AK) inflammation led to the development of topical fluorouracil, a product registered for the management of AK. A conscientious surveillance of AK inflammation during chemotherapy may conceivably lead to the development of further drugs for treatment of AK. A number of other chemotherapeutics have thus been linked to similar reactions without ensuing development. Here, we describe two further cases linking chemotherapy with carboplatin and paclitaxel to possible anti-AK effects, identifying them as potential treatments. Whether multidrug chemotherapy leads to stronger AK inflammation or cure AK more successfully is currently unknown.

Papular eruption on UV-exposed skin in a 7-year-old boy caused by Enterobius vermicularis infection

Enterobiasis is the most common parasite infestation in children; it is often asymptomatic and may rarely be a cause of skin eruption. We present the case of a 7-year-old boy with sudden onset of pruritic erythemato-squamous confluent papules and plaques on UV-exposed skin, caused by proven enterobiasis. To our understanding, this is the first case of photodermatosis-like dermatitis caused by enterobiasis reported in the literature.

Primary systemic amyloidosis with skin and cardiac involvement: a case report

Primary systemic amyloidosis is characterized by the deposition of insoluble monoclonal immunoglobulin light chains in various tissues and is usually associated with an underlying plasma cell dyscrasia. In the early stage of the disease, dermatological findings can be the only manifestation, as opposed to organ involvement in the later stages. A dermatologist can diagnose amyloidosis early with a skin biopsy stained with Congo red dye and other appropriate investigations. This case report describes a female patient with primary systemic amyloidosis confirmed histologically from a skin biopsy. When the diagnosis was established, cardiac involvement and monoclonal gammopathy were already present. Treatment with bortezomib and dexamethasone was initiated; due to side effects, the treatment was later switched to lenalidomide, which was better tolerated.
