Dual ectopy: Unique appearance of ectopic thyroid.

A 67-year-old female underwent a computed tomography angiogram (CTA) of the head in the setting of acute, short-term memory loss. Two lobulated hyperattenuating lesions were incidentally discovered at the base of the tongue and the hyoid bone. Upon further investigation in the outpatient setting including further imaging and ultrasound-guided biopsy, the lesions were confirmed to be ectopic thyroid tissue with dual ectopy.

Warm autoantibodies mimicking alloantibodies: Three cases of autoantibodies with unusual antigenic specificity.

Objectives: We describe 3 cases of red blood cell (RBC) autoantibodies with unusual apparent antigenic specificity and discuss the testing methodology and implications of these findings.

Methods: All immunohematologic testing, including ABO and RhD typing, antibody detection and identification, RBC antigen phenotyping and genotyping, direct antiglobulin tests, and elution studies were performed using standardized and validated methods and reagents.

Results: Three patients were found to have autoantibodies, which were originally presumed to be alloantibodies.

Pulmonary Metastases From Primary Thigh Leiomyosarcoma: A Case Report and Review of the Literature.

Leiomyosarcoma is a rare type of tumor of smooth muscle cells that can occur anywhere in the body. However, it typically occurs in the retroperitoneum, intra-abdominal sites, and uterus in people over 65. Here is a case of a 71-year-old male with a history of melanoma of the skin who presented with a rapidly enlarging, non-tender lump at his left lateral thigh area that was later diagnosed as pleomorphic dedifferentiated leiomyosarcoma.

An Unusual Case of Lung Adenocarcinoma Metastasis to the Tricep Muscle: Four Years Disease-Free After Surgical Resection and Radiotherapy.

Lung cancer is one of the leading causes of cancer-related death worldwide. Lung cancer commonly metastasizes to the liver, bone, and brain, but metastasis to skeletal muscles is rare. The development of metastasis in skeletal muscles indicates stage IV disease with a poor prognosis.

Anaplastic Large-Cell Lymphoma (ALCL) First Manifested as a Rapidly Progressive Acute Respiratory Failure (RF): Lymph Node Biopsy Negative Presentation Posing a Diagnostic Challenge.

Anaplastic large-cell lymphoma (ALCL) is an aggressive subtype of non-Hodgkin lymphoma. There are two forms of ALCL: primary and secondary. Primary can be systemic, affecting multiple organs, or cutaneous, affecting mainly the skin.

Sporadic insulinoma in a 10-year-old boy: a case report and literature review.

Context: Insulinoma is an exceedingly uncommon pancreatic islet cell neuroendocrine tumor. Its estimated incidence is approximately four cases per million individuals per year.

Case Report: We report the case of sporadic insulinoma in an exceptionally very young 10-year-old boy who presented with a 1-month history of episodic tremulousness, diaphoresis, increased hunger, confusion and fainting.
