Large-cell neuroendocrine carcinoma of prostate. Case report.

Objective: To report a case of a neuroendocrine differentiation in a prostate cancer patient, a rare subtype.

Methods: We describe the case of a patient diagnosed with adenocarcinoma of the prostate initially, who presented hematuria due to disease progression with neuroendocrine differentiation despite androgen-deprivation therapy (ADT ).

Discussion: Prostate cancer is the most common tumor in men.

Intestinal uptake of (99m)Tc-MDP: a case report of protein-losing enteropathy correlated with pathology findings from autopsy.

We present a case of a 60-year-old man with a history of severe hypoproteinemia and constitutional syndrome, suspected to have protein-losing enteropathy (PLE). Bone scintigraphy ((99m)Tc-MDP) performed to rule out the presence of bone metastases incidentally showed abnormal uptake in abdominal soft tissue. The patient unexpectedly died of heart failure, and autopsy revealed microscopic alterations consistent with PLE exclusively in the right colon, corresponding to the area of abnormal uptake.

[Management of lymphoid hyperplasia of the ocular adnexa].

Objective: Lymphoid Hyperplasia (LH) is a benign proliferative lymphocyte-rich process. Histologically, LH may be similar to a lymphoma. Its incidence has decreased because of new sophisticated diagnostic procedures and a better knowledge of lymphomas.

[Low-grade oncocytic adrenal carcinoma].

Objective: To report a case of left adrenocortical neoplasm.

Methods: A case of left adrenocortical neoplasm measuring 16 x 10 x 7 cm in a 47-year-old male is presented. After puncture biopsy, a left adrenalectomy through the abdominal approach was performed.
