ABSTRACT

In the present study, the immunoprofile of chronic sclerosing sialadenitis, also known as Kuttner tumor, was analyzed. Two cases that occurred in the submandibular gland of male patients were submitted to immunohistochemical reactions to different antibodies. Histological examinations showed a submandibular gland exhibiting various degrees of atrophy with destruction of acini, infiltration by inflammatory cells, and periductal fibrosis. Reactions to cytokeratins (CKs) showed acini and duct remnants positive to CKs 7, 8, 19, and 13. CK14 stained myoepithelial cells around preserved acini and intercalated duct, and also basal cell of excretory ducts, but was negative in proliferating and branching ducts. Smooth muscle actin (SMA) was expressed by myofibroblasts in periductal fibrosis, and an intense expression of extracellular components was also seen. Lymphocyte markers showed, besides mature follicles, a higher presence of CD45RO positive cells. Thus, the immunoprofile of Kuttner is much more in keeping with an inflammatory-induced degenerative disease than with a preneoplastic lesion.

ABSTRACT

Entre las principales enfermedades oportunistas que aparecen en el paciente VIH-positivo se encuentra la histoplasmosis. Esta micosis sistémica, causada por el hongo Histoplasma capsulatum, tiene la capacidad de diseminarse a partir del pulmón hacia la piel y la mucosa oral. Pueden encontrarse lesiones orales de histoplasmosis con aspecto ulcerado o nodular, pero son siempre muy dolorosas e infiltrantes de la mucosa. Cuando están presentes en la boca son claro indicio de alguna inmunodepresión. Este trabajo muestra la evolución de un paciente VIH-positivo que presentaba varias lesiones ulceradas en la cavidad bucal y la piel facial. La sintomatología y el aspecto clínico de las lesiones no fueron específicos de la enfermedad y por eso el diagnóstico fue obtenido por raspado citológico y biopsia oral. El resultado de los exámenes puso de manifiesto que se trataba de un cuadro sistémico. El plan de tratamiento fue hecho con anfotericina B para la remisión de las lesiones y, seguidamente, con itraconazol en la fase de mantenimiento (AU)
