Sinonasal Adenocarcinoma: Clinicopathological Characterization and Prognostic Factors.

Sinonasal (SN) malignancies are rare. Within SN adenocarcinomas, the most frequent are intestinal-type adenocarcinomas (ITACs). ITAC has been associated with wood and leather dust occupational exposure and TP53 mutations.

Baseline anaemia increases locally advanced rectal cancer mortality in older patients undergoing preoperative chemoradiation.

Purpose: The median diagnosis age of rectal cancer (RC) is 70 years old. The standard of care for locally advanced RC (LARC) is preoperative chemoradiation (CRT) followed by surgery. Anaemia is a frequent condition in older patients but is not a pure consequence of ageing.

Ectopic Cushing's Syndrome Unveiling a Metastatic Parotid Carcinoma.

Introduction: Adrenocorticotropic hormone (ACTH) ectopic production is a rare cause of Cushing syndrome (CS). The most commonly associated tumours are small-cell lung carcinoma along with bronchial and thymic carcinoids. To date, only 5 cases have been published in the literature featuring ectopic ACTH secretion from metastatic acinic cell carcinoma (ACC) of the parotid gland.

Large desmoid tumors in familial adenomatous polyposis: a successful outcome.

Desmoid tumors develop from connective tissue, fasciae, and aponeuroses, and may occur in the context of familial adenomatous polyposis or may arise sporadically; also, they may be extra-abdominal, intra-abdominal, or located in the abdominal wall. These benign tumors have a great aggressiveness with a high rate of local recurrence. Familial adenomatous polyposis is an inherited condition with autosomal dominant transmission, and is characterized by the development of multiple colonic and rectal adenomatous polyps, as well as desmoid tumors.

Treatment of Head and Neck Cancer with Photodynamic Therapy with Redaporfin: A Clinical Case Report.

Advanced head and neck squamous cell carcinoma, after locoregional treatment and multiple lines of systemic therapies, represents a great challenge to overcome acquired resistance. The present clinical case illustrates a successful treatment option and is the first to describe the use of photodynamic therapy (PDT) with Redaporfin, followed by immune checkpoint inhibition with an anti-PD1 antibody. This patient presented an extensive tumor in the mouth pavement progressing after surgery, radiotherapy, and multiple lines of systemic treatment.

Small cell neuroendocrine carcinoma of the nasopharynx: a rare case report.

Small cell neuroendocrine carcinoma rarely appears primarily in the head and neck and exhibits aggressive behavior with a poor prognosis. The pathologist has a significant role in the diagnosis, and a consensual treatment still does not exist. The authors report the case of a middle-aged male patient who presented repeated episodes of massive epistaxis.

Colon stenosis in a patient with ulcerative colitis as a manifestation of mixed müllerian tumor of the peritoneum.

We report the case of a 56-year-old woman followed for ulcerative colitis since 1987. In 1993, she underwent a total hysterectomy with bilateral salpingo-oophorectomy. In 1996, a narrowing of the lumen at 20 cm of the anal margin was observed and she was put under endoscopic observation.
