| Popis: | Squamous odontogenic tumor-like proliferations (SOT-LPs) are an uncommon histopathological finding occurring in the fibrous capsule of odontogenic cysts, which share certain microscopic features with squamous odontogenic tumor (SOT). A 36-year-old woman presented with an 18-month history of a painless, slow-growing swelling in the maxilla. Her medical history was unremarkable. Computed tomography revealed a well-defined, unilocular hypodense lesion extending from nonvital tooth #21 to tooth #11, with expansion and rupture of vestibular cortical bone, measuring approximately 1.5 cm. Under the diagnostic hypothesis of radicular cyst, an excisional biopsy was performed. Histopathological analysis disclosed a cystic cavity lined by nonkeratinized stratified squamous epithelium exhibiting hyperplasia, exocytosis, and spongiosis. The fibrous capsule revealed conspicuous islands of well-differentiated squamous epithelium, some of them exhibiting foci of microcystic degeneration. The final diagnosis was radicular cyst with SOT-LPs. The patient remains under close follow-up. |
