TL;DR: Laryngeal small cell neuroendocrine carcinomas are chiefly treated by way of radiation and chemotherapy; the role of adjuvant therapy in the treatment of atypical carcinoid tumours remains to be established.

TL;DR: The entity known as sinus histiocytosis with massive lymphadenopathy (SHML), or Rosai-Dorfman disease, is an uncommon benign proliferation of hematopoietic and fibrous tissue that often presents in the head and neck region.

TL;DR: It is concluded that wide local excision for early-stage buccal carcinoma is associated with a high local failure rate and possible causes for failure and alternative treatment approaches are discussed.

TL;DR: Myofibromatosis is a distinct disorder among the great number of fibrous proliferations occurring in infants and children, with a particular predilection for the head and neck region, and many of these lesions show spontaneous regression, suggesting that lesions not affecting vital functions, resulting in growth anomalies, or demonstrating rapid aggressive growth may be managed conservatively.

TL;DR: Parathyroid carcinoma is a rare entity, comprising fewer than 1% of cases of hyperparathyroidism and occasionally with vocal cord paralysis or a firm palpable cervical mass.
