Ectopic thyroid tissue results from abnormal embryologic development and migration of the thyroid gland. True malignant transformation in ectopic thyroid tissue is extremely rare and is always diagnosed after surgical excision of the lesion by pathology examinations. There are well-documented cases of ectopic thyroid cancer while primary tumoral lesion occurs in the orthotopic thyroid, but only...

The aim of this study was to analyze whether tyrosine phosphorylation in tumoral arteries may modulate their vascular response. To do this, mesenteric arteries supplying blood flow to colorectal tumors or to normal intestine were obtained during surgery and prepared for isometric tension recording in an organ bath. Increasing tyrosine phosphorylation with the phosphatase inhibitor, sodium ortho...

We present a unique case of tumoral calcinosis (TC) with airway involvement and a novel technique for debridement. TC is a rare disorder, characterized by calcified tumors and dysfunction of large joints. To date there have been no reports of calcification involving the airway. CD is a 43 year old male with a long history of TC who developed dysphagia prompting otolaryngic evaluation. He was fo...

The authors report a case of asymptomatic leukemic optic neuropathy as the first sign of acute lymphoblastic leukemia relapse in a 4-year-old boy. Routine ophthalmologic examination showed normal visual acuity and pupillary function in the presence of a tumoral mass covering the left optic disc. The mass resolved with preservation of vision after intrathecal chemotherapy. A routine ophthalmolog...

Solid and papillary epithelial neoplasm of the pancreas (SPEN) is an encapsulated, slowly enlarging abdominal mass that generally shows no evidence of capsular invasion, regional lymph node involvement, or distal metastases. We present a 68 years old Hispanic male diagnosed with SPEN 5 years earlier that refused surgical excision. Presently he underwent a whole-body 18F-FDG PET/CT. Although tum...

Serous borderline ovarian tumors (SBOT) generally occur in young women, present at early stages and are associated with an excellent prognosis. However, there are rare subtypes of SBOT which may exhibit a more aggressive course. In contrast with other types of SBOT, the micropapillary variant SBOT (SBOT-MP) tends to present at advanced stages. Herein, we present a rare case of a SBOT-MP that oc...

We present the case of a 71-year-old woman diagnosed with diffuse large B-cell non-Hodgkin lymphoma, stage IV-B, IPI 3, in complete remission after 6 cycles of rituximab-CHOP. Fivemonths after completing treatment the patient went to the Emergency Department for a picture of headache and diplopy of one month of evolution. During admission she present lumbosciatalgia refractory to pharmacologic ...
