RESUMEN
Strongyloides is a unique nematode in its ability to cause a secondary hyperinfection and disseminated disease several years following initial contact. The prevalence of Strongyloides infection has been rising; it is currently considered a global disease, which presents with a broad spectrum of clinical signs and symptoms among patients. This case report focuses on a 67-year-old Caribbean female presenting with severe weight loss, vomiting, early satiety, and mild anemia who was subsequently diagnosed with strongyloidiasis on the basis of a duodenal biopsy pathology report obtained via esophagogastroduodenoscopy (EGD).
RESUMEN
The blue nevus is a well-described benign melanocytic proliferation that generally occurs on the skin. Infrequently, blue nevi are found on mucosal surfaces. The most common location for mucosal blue nevi is the oral mucosa, with reported cases in the sinonasal mucosa and genital tract, as well as in other locations. To our knowledge, blue nevi of the rectal mucosa have not been described. Here, we describe a case of blue nevus arising in the rectal mucosa. Blue nevi are benign melanocytic proliferations with the potential for malignant transformation and should be included in the differential diagnosis of pigmented mucosal lesions of the rectum.

Nontraumatic myositis ossificans circumscripta (MOC) is a rarely reported benign heterotopic ossification characterized by the aberrant formation of bone in extraskeletal soft tissues. Although a history of trauma can be elicited in 75% of MOC patients, the etiology is unclear in patients without inciting injury. MOC is associated with young male athletes, and is most often localized to the muscle groups of the extremities. Rare cases have been reported in children and adolescents of nontraumatic MOC in the neck. We present a 15-year-old adolescent with a rapidly growing, painful neck mass without traumatic stimulus.
