Maxillary sinus squamous cell carcinoma during pregnancy: a new case report
Less than one percent of malignant lesions are malignant tumors of the paranasal sinuses. The majority of maxillary sinus carcinomas are squamous cell carcinomas (SCC). There are few reports of head and neck SCC found during pregnancy; however, in this article, a 23-year-old woman in the fourth month of pregnancy was diagnosed with a maxillary sinus SCC. The histopathologic evaluation of the lesion showed a malignant proliferation of squamous cells with a sheath and cord formation that invaded the surrounding tissue. These findings were compatible with SCC. Hemimaxillectomy, neck dissection, and chemoradiotherapy were conducted; however, despite these therapeutic interventions, the patient died 11 months after the initial visit due to distant metastasis
Computed Tomographic findings of maxillofacial SCC and Undifferentiated carcinoma
Abstract:Objectives: Tomographic findings contribute enormously to the accurate diagnosis of malignant lesions in due time and/or at imminent stages. This study investigates CT-scan findings of maxillofacial SCC and undifferentiated carcinoma.Study design:  CT images of 61 maxillofacial malignant tumors included 42 SCCs and 19 undifferentiated carcinomas were evaluated based on the location, internal density, border, bone destruction and expansion, periosteal reaction, emphysema, calcification, loss of facial and fat plane, and fat plane reticulation, by two expert radiologists separately. The data were analyzed, using Chi-square and Fisher’s exact test.Results: Isodense/homogeneous (78.7%) and total heterogeneous enhancement (87.8%) appearance were the most common internal patterns detected before and after injection of contrast, respectively. There was a significant association between borders and pathology of our two lesions (p= 0.007).Conclusions: It is highly unlikely to diagnose the tumor histopathology based merely on its tomography patterns; however it is feasible to determine its aggressive nature.     Key words: Computed tomography, SCC, undifferentiated carcinoma, maxillofacial regio
