Pituitary metastasis: a rare condition
Tumor metastasis to the pituitary gland is a rare, not well-documented and life-threatening condition associated with a shortened life span. A better understanding of its clinical manifestations could lead to earlier diagnosis, appropriate therapy and potentially improving quality of life. Therefore, we retrospectively studied the charts of patients with pituitary metastases who were treated at the City of Hope National Medical Center (Duarte, CA) from 1984 to 2018. We reviewed and analyzed tumor origin, primary pituitary clinical manifestation, duration between primary tumor diagnosis and pituitary metastasis, type of treatment and patient survival. A total of
11 patients were identified with a mean age of 59.2Â years and median survival following the diagnosis of metastasis of 10Â months. Breast cancer and lymphoma were the most common primary origins in these cases, and diabetes insipidus and panhypopituitarism were the most common clinical manifestations of their metastasis. We also compared our results with reports in the literature published between 1957 and 2018. A total 289 patients with pituitary metastasis have been reported in the literature. Breast cancer was the most frequent primary origin of the metastasis, and visual symptoms were the most common primary manifestation. The posterior part of the pituitary is more susceptible than the anterior to metastasis. Pituitary metastasis may occur as a consequence of successful primary tumor treatment prolonging the chance of seeding. Future studies are needed to determine the molecular mechanism of metastasis to the pituitary
Adenovirus 36 DNA in Adipose Tissue of Patient with Unusual Visceral Obesity
Massive adipose tissue depositions in the abdomen and thorax sufficient to interfere with respiration developed in a patient with multiple medical problems. Biopsy of adipose tissue identified human adenovirus 36 (Adv 36) DNA. Adv 36 causes adipogenesis in animals and humans. Development of massive lipomatosis may be caused by Adv 36
Only a Train Can Mask Another Train
A 36-year-old man presented with fever, abdominal pain and diarrhea reportedly lasting for the past three months. Originally an immigrant from Mexico, he had been living in California for the past four years and made a recent trip back to Guerrero, Mexico. On admission, the patient was febrile (41°C), hypotensive (94/54 mmHg), tachycardic (118 beats/min) and tachypneic (36 breaths/min). Multiple bilateral cervical and axillary lymph nodes were palpated. Other findings included crackles in the bases of both lungs and a large mass in the left hypochondrium
