Human myiasis is a parasitosis usually found in tropical and underdeveloped countries. It usually affects ulcerated lesions or devitalized tissues, developing after deposition of dipterous eggs. Patients with head and neck cancer are at risk to develop secondary myiasis. A representative percentage of those patients manifest with neglected and advanced tumors, usually in exposed areas and with necrotic tissues. Few case reports and small series constitute the available information about this parasitosis. Most studies have been conducted in patients with skin carcinomas, although myiasis has already been described in association with other head and neck malignancies. The authors present a series of 12 cases of myiasis secondary to head and neck cancer in addition to a literature review.

A high proportion of papillary thyroid carcinoma cases are associated with Hashimoto's thyroiditis. There are associations among these cases with several histopathological factors already recognized for their prognostic value, which by themselves could impact outcomes.

The game could be applied to other undergraduate courses in the field of Health Sciences.

A small percentage of papillary carcinoma cases is represented by variants recognized by their greater potential for aggression. There are associations between these variants and several other histopathological factors already recognized for their prognostic value, which may, by themselves, influence the outcome of these cases.
