Myoepithelioma (ME) is a benign tumor, arising predominantly from major and minor salivary glands (SG). Clinically, it presents as a painless mass with a slow growth. In our case report, this lesion occurred in a 51-year-old man, and presented as a well-defined oval mass on the right parotid region. The magnetic resonance imaging study confirmed the presence of a lesion with benign features that was excised surgically by partial superficial parotidectomy. The histopathological and immunohistochemical analysis confirmed the diagnosis of parotid ME. Other SG tumors such as pleomorphic adenoma are differential diagnoses of ME. Complete surgical excision reduces the rate of recurrence.
<p class="abstract">Nasal lobular capillary hemangioma (LCH) is a rare and benign vascular tumor of unknown etiology, often associated with hormonal factors and a history of trauma. In this case series we present twelve cases of nasal LCH diagnosed on patients treated at the Hospital da Senhora da Oliveira from January 2010 and December 2019. Of the 12 patients, 66, 7% were males. The most common clinical presentation was epistaxis (75%) followed by nasal obstruction (50%). In 75% of patients the most commonly affected area was the nasal septum. Regarding proposed contributing factors, nasal trauma was the most prevalent (33%), followed by the use of oral contraceptives (25%) and pregnancy (8.3%). Endoscopic sinus surgery was performed in all patients, with complete excision of the lesion, and no post-operative complications were observed. Nasal LCH should be considered in the differential diagnosis of nasal vascular lesions associated with unilateral epistaxis and nasal obstruction. Complete surgical resection should be the treatment of choice, since it’s associated with lower risk of recurrence.</p>
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
