Black-spot poison ivy is an uncommon presentation of poison ivy (Toxicodendron) allergic contact dermatitis. A 78-year-old sought evaluation of a black spot present on her right hand amid pruritic vesicles. The presentation of a black spot on the skin in a clinical context suggesting poison ivy is indicative of black-spot poison ivy. ⋯ A skin sample was obtained and compared against a poison ivy standard using ultra-fast liquid chromatography-tandem mass spectrometry (UFLC-MS/MS). This finding confirmed the presence of multiple urushiol congeners in the skin sample. Black-spot poison ivy may be added to the list of diagnoses that show a specific dermoscopic pattern.

Review Case ReportsFacial chromoblastomycosis in sub-Himalayan region misdiagnosed as cutaneous leishmaniasis: brief report and review of Indian literature.
Cases of chromoblastomycosis, although not uncommon, have rarely been reported in the literature from our region. These are usually misdiagnosed as cases of cutaneous leishmaniasis because we reside in an endemic region for this disease. ⋯ A biopsy revealed these to be cases of chromoblastomycosis, after which the patients were started on antifungal agents. There was marked improvement after the correct treatment was initiated.
