Oral squamous cell carcinoma (OSCC) is an extremely rare occurrence during pregnancy. OSCC accounts for less than 2% of all malignancies in pregnant women, with an average mortality rate of 36%. Understanding the features of this tumor during pregnancy is important; however, the paucity of reports in the literature makes this challenging. Case presentation: The following is a case presentation of a woman who was diagnosed with SCC of the tongue (TSCC) at 13 weeks gestation. The article also provides a review of the literature of TSCC affecting pregnant women aged 30 years and under. Conclusion: Although OSCC in young women of reproductive age is rare, recent literature suggests an increased risk for this age group. The rarity of OSCC in pregnancy may potentially lead to low clinical index of suspicion, misdiagnosis, and delay in treatment. Additionally, treatment modalities, prognosis, and the long-term impact on the developing fetus are not well established, due to rarity of OSCC in pregnancy. Further studies to identify specific etiologic factors are needed to establish the association of OSCC with pregnancy, aid in prevention, and improve treatment and outcome.

To the authors' knowledge, this is the first reported case of an odontogenic carcinoma with documented skeletal muscle differentiation (rhabdomyosarcoma). The histology and clinical features of this aggressive odontogenic neoplasm are described. Within the English-language literature, only 2 cases are reported of an odontogenic tumor with muscle differentiation: a benign odontogenic tumor (ameloblastoma) with differentiation into a rhabdomyosarcoma and an odontogenic sarcoma with smooth-muscle differentiation. The general practitioner should be aware that odontogenic lesions may be malignant, even though this is extremely rare, and all tissue removed from the oral cavity should be submitted for biopsy.
