Trichophyton rubrum is a common agent found in superficial mycoses, which present ample non-inflammatory lesions, with chronic evolution, especially in immunocompromised patients. The hypercortisolism in Cushing's syndrome increases the risk of infections as a result of the immunosuppressive effect of glucocorticoids. The reported cases here refer to two different types of dermatophytosis cause...

The curative treatment of Cushing's disease is surgery, mainly transphenoidal surgery. The cure probability is high and the risks or complications are few. However, pharmacotherapy is necessary while localisation of the secreting tumour is not achieved, when there is persistence of hypercortisolism after surgery, or while waiting for effectiveness of radiotherapy. We review the existing drugs, ...

ABSTR ACT: Cortisol production is normally under the regulation of adrenocorticotropic hormone (ACTH). Hypercortisolism or Cushing’s syndrome, characterized by excessive cortisol levels, may be caused by ACTH-independent mechanisms. The present work aims to review the current knowledge on ACTH-independent mechanisms through aberrant expression of hormone receptors in adrenal tumors and adrenoco...

Feline pituitary tumors are rare. An 8-year-old male Japanese domestic cat presented with anorexia and emaciation. The cat died 17 days after admission from progressive neurological symptoms. At necropsy, a pituitary tumor measuring 25 × 18 × 15 mm was found. Microscopically, the tumor was divided into multiple lobules and had grown invasively into the adjacent brain tissue and sphenoid bone. T...
