RESUMO
Scedosporium prolificans (S. prolificans) is an increasingly prevalent and treatment-resistant opportunistic fungus. The pathogen is known to cause a variety of clinical manifestations ranging from localized cutaneous disease to disseminated systemic infection. Herein we present an otherwise healthy 41-year-old male with biopsy-proven S. prolificans cutaneous infection. The patient experienced drastic clinical improvement on two months of a combination of oral itraconazole and oral minocycline. S. prolificans exhibits resistance to many antifungal agents, thus, single-agent antifungal therapy has a high failure rate and often results in the need for surgical excision or debridement. Recent accounts suggest that minocycline in combination with azole antifungals has a synergistic effect in treating S. prolificans. This case highlights the excellent response to combination oral therapies with minocycline and itraconazole. Prompt and efficacious treatment reduces the risk of destructive or disseminated disease and may avoid the need for surgical intervention.
RESUMO
Erythema annulare centrifugum (EAC) is a figurate erythema presenting with annular, erythematous plaques with a trailing scale. It is considered a hypersensitivity reaction to a variety of antigens and is associated with multiple underlying causes including malignancy. Malignancy-associated EAC is termed paraneoplastic erythema annulare centrifugum eruption (PEACE). Although a specific etiology has yet to be elucidated, this form of EAC is likely to occur due to cytokine and/or antigen stimulation from an underlying malignancy. PEACE is primarily associated with lymphoproliferative disorders and rarely solid tumors. Our report discusses a case of PEACE associated with metastatic colorectal adenocarcinoma. On presentation to our clinic, the patient had developed a migratory annular eruption over a year. His review of symptoms was positive for signs of underlying malignancy, including weight loss and recent lower vertebral fracture. A biopsy of his annular lesion revealed a non-specific pityriasiform dermatitis. A vertebral biopsy uncovered a diagnosis of metastatic colorectal cancer. At that time, clinicopathologic correlation allowed us to reach the diagnosis of PEACE.
RESUMO
A cystic panfolliculoma is a benign follicular neoplasm which recapitulates several portions of the hair follicle. The patient was a 64-year-old Caucasian female who presented with a new growth on her right forearm. The lesion had slowly enlarged over the previous 11 months. She complained of it bleeding on several occasions and being very tender when touched. On exam was an 8 mm firm pink papule which appeared slightly eroded. The growth was excised in clinic. Histology showed a well-circumscribed neoplasm with foci of matrical, infundibular, inner and outer root sheath differentiation. A BerEp3 labeled focal areas of follicular germinative differentiation at the periphery of the proliferation. The lesion was narrowly excised in the available planes of section. The surgical site healed well and there are no residual symptoms from the tumor.
