Pleomorphic adenoma of the lower lip: A rare site of location

Abstract

Context:Pleomorphic adenoma is the most common neoplasm of the minor salivary glands which are uncommon among the entire salivary gland tumors. The lower lip is a very rare site of occurrence for pleomorphic adenoma. We intended to present a case of pleomorphic adenoma of the lower lip.Case Report:A 49-year-old Turkish man presented with the painless mass on his lower lip. A total excision was choiced for the mass by both we and the patient because of some cosmetic reasons. The histopathological evaluation revealed the diagnosis of pleomorphic adenoma and neither complication nor recurrence was observed during a clinical follow-up for 40 months.Conclusions:A clinician should be vigilant for the possibility of existence of a pleomorphic adenoma located on the lower lip even it is rare. Once it is diagnosed concisely, a wide excision is suggested in general if there is no cosmetic care and no risk of damage to functional structures of head and neck.

Pleomorphic adenoma of the lower lip: A review

“…Macroscopically, PA is a well-circumscribed, round to oval mass[ 1 10 ] having white to tan cut surface, often shiny to translucent. The encapsulation is quietly variable and the multifocality is frequent in the recurrent tumors.…”

“…Microscopically, they exhibit a varied histologic structure. However, all expose the epithelial ductal structures, myoepithelial cells, and a mesenchymal stroma[ 1 10 ]. They can be divided into three groups: 1) myxoid (80 % stroma), 2) cellular (80 % cellular), and 3) mixed (classic).…”

“…The histopathological evaluation revealed the diagnosis of PA. The patient recovered uneventfully and neither complication nor recurrence was observed during a clinical follow-up for 47 months[ 10 ].…”

“…A primary suturation of the incision, we also perform like that ( Figure 2 ), is enough following this technique. Disadvantages of a wide excision of extra-major salivary gland PA can be outlined as cosmetic care particularly for the upper and lower lips, eyes, and face in general[ 10 22 ]. Besides these, the probability of an injury to the functional structures of the head and neck such as the upper and lower lip, and palate should be also included in disadvantages.…”

Fibrolipoma of Lip in a Young Individual: A Rare Presentation

“…A clinical differential diagnosis of fibroma, mucocele, and lipoma was made. However, other rare lesions of the lower lip reported in literature, which include schwannoma, 8 traumatic neuroma, 9 and salivary gland neoplasms, 10,11 were also considered in the clinical differential diagnosis. The lesion was surgically excised under local anesthesia (Fig.…”
