Teratomas and dermoids or hairy polyps of the head and neck are rare congenital tumours, often confused and reported to appear as single masses, that may cause upper aerodigestive tract impairment. Their histological classification, origin and embryological basis of development have been a topic of debate in the past and recent literature.

We report a case of an infant presenting with a multifocal bigerminal teratoma in the nasopharynx and the neck, causing a deep neck infection, and discuss the unique clinicopathological aspects of this case.

Laryngeal squamous cell carcinoma (SCC) is one of the most frequent malignancies in the head and neck region. The risk of multiple malignancies is reported as 2–11 per cent and most of the second primaries are SCCs. Lymphogenic tumours as second primaries are extremely rare. In this paper, we report a case of laryngeal SCC with synchronous non-Hodgkin's lymphoma and review the literature on the clinical and histopathological aspects of these malignancies.

Synchronous laryngeal malignancies are extremely uncommon. To the best of our knowledge, only four cases of primary synchronous squamous cell carcinoma (SCC) of the larynx are available in the literature. We report the case of a 52-year-old patient with simultaneous spindle-cell carcinoma and SCC in situ of the larynx. The pathogenesis, treatment and prognosis of this rare occurrence have been discussed.
