An uncommon case of fibrolipoma

Fibrolipoma of the lower lip: A case report and review of the literature

BACKGROUND

Fibrolipoma of the lower lip is an uncommon condition with limited documentation in the literature. This paper provides updated insights into oral and maxillofacial lipomas through a detailed case report and comprehensive literature review, discussing clinical features, pathogenesis, diagnostic approaches, histopathology, and therapeutic strategies.

CASE PRESENTATION

A 54-year-old female presented with a painless, enlarging mass on the inner aspect of her right lower lip, first noticed 2 years prior. The mass, now the size of a peanut, interfered with her eating and speech. Physical examination revealed a 2.0 × 2.5 × 1.0 cm mass beneath the mucous membrane of the right lower lip. It was firm, well-demarcated, and mobile. Surgical excision was performed, and histopathological analysis confirmed the diagnosis of a lower lip fibrolipoma. The lesion was successfully removed without recurrence.

CONCLUSION

Lipomas in the oral and maxillofacial regions are rare, slow-growing benign tumors, particularly within the lips. Although their diagnosis is straightforward based on clinical presentation, histopathological confirmation is essential. Surgical resection remains the treatment of choice, with excellent prognostic outcomes.

Rare fibrolipoma of attached gingiva: A case report and review of the literature

Lipoma is a rare benign tumor. Fibrolipoma, a variant of lipoma, is relatively uncommon in mouth tissues. Among all benign lesions of oral cavity, the approximate incidence rate of lipoma is 1%-4%, with a prevalence rate of about 0.0002%. Fibrolipoma is an extremely rare subtype of lipoma, especially in the attached gingiva. This subtype accounts for 1.6% of all facial lipomas, with a prevalence rate of 1/5000 adults in the oral and oropharyngeal region. It is diagnosed by histopathologic and immunohistochemistry evaluation and treated by total excision. Due to the adhesion to the surrounding tissues and pseudo-infiltrating characteristics of this lesion, it can get mistaken with malignant lesions; therefore, a histological examination is mandatory. In this paper, a case of a patient with attached gingiva fibrolipoma treated by surgical excision is reported. This case report is about a 26-year-old female patient in Shiraz School of Dentistry with a fibrolipoma of attached gingiva. Because of fibrolipoma's growth tendency, adhesion to the surrounding tissues, and specific histological characteristics, its differential diagnosis with malignant infiltrating tumors is important. Surgical excision is the gold standard for treatment. Accurate differential diagnosis, careful histological examination, and periodic follow-up are essential.

Fibrolipoma presenting as a posterior nasal septum mass: a report of a unique case and review of the literature

Unilateral sinonasal mass presenting as nasal block is a common presentation but poses a diagnostic challenge. The differential diagnosis includes inflammatory polyps, benign and malignant sinonasal neoplasm. Fibrolipoma presenting in the sinonasal area is an uncommon pathology. As it is uncommon, there is potential for a misdiagnosis, unnecessary investigation and delay in the definitive treatment. We report a patient with a fibrolipoma originating from the posterior nasal septum. The diagnostic and surgical features of this unique case are discussed.
