Penile strangulation by hair coil is an uncommon, under-recognized condition with a spectrum of potential complications including urethral transection and partial or complete penile amputation. Early recognition and treatment can greatly reduce the incidence of these devastating complications. We report a 5-year-old, circumcised boy with penile edema and erosions secondary to a hair wrapped around the coronal sulcus. Prompt diagnosis and removal of the hair led to rapid resolution without surgical repair. We also analyze the possible underlying causes which can lead to strangulation of the penis with a hair.
months. No cause could be found despite multiple investigations. There was poor response to medication. The child was referred to dermatology for the evaluation of a rash that had developed over the past 1 month. According to her mother, the rash appeared as erythematous papules in crops and then resolved with scars. Examination revealed multiple painful erythematous papules scattered over the limbs in different stages of evolution (Figure 1). Some were raised whereas others were umblicated in the center with a necrotic base. Healed lesions appeared as whitish, porcelain-like macular scars (Figure 2). Systemic examination was normal. Her complete blood count, renal functions, liver functions, abdominal sonography and barium meal follow-through, and coagulation profile including the international normalized ratio and serum antinuclear antibody revealed no abnormality. Skin biopsy showed a thin epidermis with hyperkeratosis overlying a necrobiotic dermal collagen with sparse inflammatory infiltrate. The blood vessels were dilated with swelling of endothelial cells and luminal thrombosis. Scattered mucin deposits were also seen. Based on historical features, characteristic skin lesions, and a supportive histology, the patient was diagnosed with Degos disease. Aspirin (3 mg/kg) and dipyridamole (5 mg/kg) were prescribed. Within 48 hours, the patient improved. Irritability reduced significantly. Active lesions started healing. Abdominal pain improved but vomiting continued although frequency was reduced significantly. At the time of reporting, the patient is still admitted in our pediatric
Asymmetrical periflexural exanthem is a rare clinical condition, seen almost exclusively in children. Very few adult cases have been reported in the literature. We report a case of this rare eruption in an adult man showing characteristic clinical and histological features. Interestingly, this patient also exhibited a pseudoisomorphic Köebner response. Although an infective aetiology of viral origin has been suggested for this localized eruption, the aetiology remains unknown. We are of the opinion that the pseudoisomorphic Köebner response in this patient may support the inoculation hypothesis in the pathogenesis of this disorder.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
