Bullous Fixed Drug Eruption Induced by Paracetamol: Report of a Pediatric Case

Drug eruptions are among the most common adverse drug reactions, affecting approximately 3% of hospitalized patients. A fixed drug eruption (FDE) is a distinct drug-induced reaction pattern that characteristically recurs at the same skin or mucosal site. We report a case of a 2-year-old girl with bullous FDE due to Tachipirina syrup, a preparation containing paracetamol, a commonly used nonsteroidal anti-inflammatory drug in Italy

Zoon's Balanitis: Benign or Premalignant Lesion?

Zoon's balanitis or balanitis circumscripta plasmacellularis is a chronic disease of unknown origin. This condition usually manifests in middle-aged or elderly uncircumcised men. Although of unknown etiology, different factors have been reported to be involved in its genesis (local infections, poor hygiene, heat, friction, and constant rubbing). It is generally considered to be a benign condition, and its association with malignancies has been rarely reported. We report the case of an uncircumcised man, who developed clinically and histopathologically evident squamous cell carcinoma of the penis in an area affected by Zoon's balanitis

Cutaneous Bowen’s Disease: an Analysis of 182 Cases according To Age, Sex, and Anatomical Site from an Italian Center

Bowen's disease (BD), also known as squamous cell carcinoma in situ, is a type of non-melanocytic intraepidermal malignancy characterised by a slowly enlarging erythematous to pink, scaly patch or plaque with irregular and well-demarcated borders. These lesions are usually persistent and progressive; it has been estimated that in general population around 3% to 5% of Bowen's disease transform into invasive squamous cell carcinoma. This report describes our experience with cutaneous BD and assesses the differences found about age, sex and anatomical site. Bowen’s disease was seen more frequently in male patients rather than in female patients in contrast to what confirmed in literature - this difference is probably because being head-neck an exposed region, patients are more easily induced to autoexam and to consult the dermatologist

Tungiasis: Case Report of a Traveller to Kenya

Tungiasis is a neglected parasitic skin disease caused by the permanent penetration of the female sand flea Tunga penetrans (also called jigger flea) into the skin of its host. Growing urbanisation, improved housing and the use of appropriate footwear have presumably led to an overall reduction of the occurrence of this ectoparasitosis within the last few decades. However, it is still highly prevalent in regions where people live in extreme poverty, such as in many Latin American and African countries [1, 2]. We report the case of a 44-year-old woman who returned from an excursion trip to Kenya's savannah with an infection of T. penetrans located on her right big toe around the nail. The natural history, pathology, epidemiology, diagnosis, therapy and control of this parasitic skin disease are discussed [1]

Ingenol mebutate for pigmented superficial basal cell carcinomas: evaluation by confocal microscopy.

The incidence of nonmelanoma skin cancer continues to increase. Surgical excision remains the best choice of treatment but the demand of patients is to have tissue-sparing approaches with good cosmetic results; these aims led to the development of novel therapeutic agents such as topical ingenol mebutate gel. We report the successful treatment with ingenol mebutate gel 0.05% of three pigmented basal cell carcinomas. Lesions were evaluated by dermoscopy and confocal microscopy before, during and after the treatment

Seven non-melanoma features to rule out facial melanoma

Facial melanoma is difficult to diagnose and dermatoscopic features are often subtle. Dermatoscopic non-melanoma patterns may have a comparable diagnostic value. In this pilot study, facial lesions were collected retrospectively, resulting in a case set of 339 melanomas and 308 non-melanomas. Lesions were evaluated for the prevalence (> 50% of lesional surface) of 7 dermatoscopic non-melanoma features: scales, white follicles, erythema/reticular vessels, reticular and/or curved lines/fingerprints, structureless brown colour, sharp demarcation, and classic criteria of seborrhoeic keratosis. Melanomas had a lower number of non-melanoma patterns (p < 0.001). Scoring a lesion suspicious when no prevalent non-melanoma pattern is found resulted in a sensitivity of 88.5% and a specificity of 66.9% for the diagnosis of melanoma. Specificity was higher for solar lentigo (78.8%) and seborrhoeic keratosis (74.3%) and lower for actinic keratosis (61.4%) and lichenoid keratosis (25.6%). Evaluation of prevalent non-melanoma patterns can provide slightly lower sensitivity and higher specificity in detecting facial melanoma compared with already known malignant features
