BACKGROUND: Histopathological analysis of tissue samples is an ancillary complementary diagnostic tool in tuberculosis (TB) with variable sensitivity and specificity according to different clinical settings. We evaluated the spectrum of histological findings, their diagnostic sensitivity, diagnostic util...

Tuberculosis is an infectious disease that involves any organ. However, the primary pituitary tuberculosis is an extremely rare disease. Intracranial tuberculomas account for 0.15-5% of intracranial space-occupying lesions, of which, pituitary as the primary site is unusual, and easily misdiagnosed as pi...

Giant cell reparative granuloma (GCRG) was first described in the 1950s. It is an uncommon and benign reactive tumor that is believed to occur after trauma or inflammation. It most commonly occurs in the maxilla and mandible and rarely affects the nasal cavity. It is often seen in children and during the...
Abstract Sarcoidosis is a multisystem granulomatous disorder of unknown aetiology. Cutaneous involvement occurs in up to 30% of patients and skin findings are often the initial presenting symptom. The facial atrophic form of sarcoidosis without associated ulceration in adolescents has rarely been describ...

Las enfermedades granulomatosas incluyen una amplia gama de enfermedades. Sin embargo, en la práctica clínica, muchos casos de enfermedad granulomatosa permanecen sin etiología después del examen histológico. Nuestro objetivo fue determinar, a partir de las biopsias de pulmón, pleura y ganglios lin...
