Sporotrichosis is a disease caused by the dimorphic fungus Sporothrix spp. The number of cases has been increasing, notedly in the city of Rio de Janeiro, Brazil, where it is now considered a public health problem. The recommended treatment employs antifungals, however in case of persistence of the lesions or when there is contraindication, cryosurgery is an option, since the fungus is sensitive to extreme temperatures. The authors report 3 cases of sporotrichosis treated for longer than 6 months with itraconazole and/or potassium iodide, all yielding incomplete response and where cryosurgery was successfully used as an adjuvant treatment.

Factitious panniculitis can be triggered by subcutaneous injections of substances linked to esthetic procedures. A case diagnosed and treated as chronic erythema nodosum manifested nodule five years later, with the anatomopathological study suggesting atypical lipomatous tumor. After resection of the lesion, histology showed steatonecrosis, compatible with lobular panniculitis. Magnetic resonance imaging examination revealed the presence of a liquid substance in the gluteal region, favoring the diagnostic suspicion of factitious panniculitis. The patient admitted to having undergone silicone injection in this region in the past, with additional findings arising from the histological review confirming this hypothesis. The late complication linked to injections of cutaneous filling material motivated the present study.

Scalp folliculitis is a common condition in dermatological practice and a diagnostic and therapeutic challenge. The authors describe a case of chronic suppurative folliculitis in a 53-year-old man who had bore the condition for 18 years. The control of chronic staphylococcal infection with sulfamethoxazole-trimethoprim for 7 months, with progressive shaving of keloid lesions (5 sessions) and application of 90% trichloroacetic acid on wounds up until re-epithelialization (7 months), were successful in treating the disease.
