Úlcera lingual asociada a paracoccidiodomicosis pulmonar / Lingual ulcer as a manifestation of systemic paracoccidioidomycosis: case report

Resumen La paracoccidioidomicosis (PCM) es una enfermedad fúngica sistémica que puede invadir cualquier órgano. Es de alta mortalidad si no es diagnosticado oportunamente. Presentamos el caso de un varón de ocupación agricultor, con antecedente de diabetes mellitus, que desarrolló inicialmente una úlcera lingual y posteriormente, una neumonía y shock séptico, sin respuesta al tratamiento antituberculoso y antibacteriano. El frotis de la secreción bronquial permitió evidenciar las levaduras en gemación múltiple, compatible con una PCM. Tuvo una respuesta satisfactoria a la administración de anfotericina B deoxicolato.

Abstract Paracoccidioidomycosis is a fungal disease of systemic involvement that can invade any organ and is of high mortality if it is not diagnosed in a timely manner. We present the case of a farmer male with a history of diabetes mellitus, who previously develops lingual ulcers and subsequently presents severe lung disease associated with septic shock, without response to antituberculous and antibacterial treatment. The bronchial secretion smear shows evidence of yeasts in multiple budding, compatible with Paracoccidioidomycosis. The patient had a satisfactory recovery to the administration of amphotericin B deoxycholate.

Methotrexate-associated Epstein–Barr virus mucocutaneous ulcer: A case report and review of literature

Epstein–Barr virus-positive mucocutaneous ulcer (EBVMCU) comprises part of the spectrum of B-cell lymphoproliferative disorders, reported in settings of immunosenescence and iatrogenic immunosuppression, affecting the oropharyngeal mucosa, skin, and gastrointestinal tract. We report a case of a 59-year-old female, known case of rheumatoid arthritis on methotrexate (MTX) for 15 years, who presented with an ulcer in the inner aspect of her cheek region for 2 years. Clinical examination revealed an infiltrative lesion involving the lower gingivobuccal sulcus of size 2 cm × 3 cm extending to the alveolus with level I lymph nodes, suspicious for carcinoma buccal mucosa. Anti-EBV-capsid antigen-immunoglobulin M and qualitative EBV polymerase chain reaction of peripheral blood were negative. Histopathological examination revealed atypical lymphoid cells with enlarged vesicular nuclei, prominent nucleoli, and moderate eosinophilic cytoplasm, few with binucleation (CD20 focally positive, CD79a focally positive, CD30+, EBV LMP-1+, MIB-I 60%) consistent with EBVMCU, MTX-associated. This is the first case report from India.
