We reviewed patients with submandibular gland pleomorphic adenoma treated at a tertiary referral centre in the United Kingdom (1988Kingdom ( -2004. Thirty-seven patients were identiWed, 32 newly diagnosed cases and 5 cases of recurrent disease previously treated elsewhere. The exact pre-operative diagnosis was "unknown" in 76% of the new cases. All cases were surgically excised (41% with extracapsular gland excision and 59% by selective level Ib, IIa and III neck dissection). Temporary marginal mandibular nerve neuropraxia was documented in 25% of cases. All 32 new cases remain clinically tumour free at the time of writing. In patients with recurrent disease, complete microscopic tumour clearance was achieved in three of the Wve cases, however all remain clinically tumour free. Pleomorphic adenomas of the submandibular gland are uncommon, with good prognosis following complete tumour excision. Recurrent tumours, however, are frequently multi-focal and diYcult to excise completely. The adequacy of primary surgery is crucial and supports an approach for a more radical excision primarily by a selective level lb, IIa and III neck dissection; ensuring complete disease clearance for pleomorphic adenoma, avoiding the risks of tumour spillage associated with a limited excision and tumour handling; and removing the primary echelon of lymph nodes at risk of metastasis if the pathology turns out to be malignant.
Pleomorphic adenoma of submandibular gland: A case report with review of literature
Dental research journal, 2014
Neoplasms that arise in the salivary glands are relatively rare, yet they represent a wide variety of both benign and malignant histologic subtypes. Approximately 70% of the salivary gland tumors affect parotid gland with the submandibular gland being affected in 5-10% of the cases, sublingual gland in 1% and minor glands in 5-15% of the cases. Submandibular gland tumors are relatively rare and very few studies have been reported in the literature that is exclusively conducted on tumors affecting submandibular gland. In this paper, we describe a case of pleomorphic adenoma affecting submandibular gland with brief review of current literature on submandibular gland tumors.
Pleomorphic Multicentric Adenoma in the Submandibular Gland
Head and Neck Pathology, 2007
Neoplasms of salivary glands represent a small group among the diseases involving the head and neck complex. In this group, the pleomorphic adenoma is the most frequent neoplasm, yet involves the submandibular gland in only 12.3% of cases. A patient presenting a swelling in the region of the submandibular gland was submitted to an incisional biopsy, where a fragment of the gland and one juxtaposed node were removed. Histologically they were defined as pleomorphic adenoma. Later, the patient was submitted to submandibulectomy and two other nodes were found close to the gland and removed. All specimens were histologically defined as pleomorphic adenoma. This multicentric finding is of great interest, perhaps explaining the recurrence rate of this neoplasm. The patient is in continuous follow-up and has not presented signs of recurrence.
Pleomorphic Adenoma of Submandibular Salivary Gland - a Case Report
International Journal of Histopathological Interpretation, 2022
Pleomorphic adenoma is a benign salivary gland neoplasm with its most common site of origin being the parotid gland, usually involving the superficial lobe of the parotid gland. Pleomorphic adenoma is a painless swelling which gradually increases in size if left untreated. It has a female predilection and occurs within the age range of 30-60 years. Here we report a rare case of a pleomorphic adenoma of the right submandibular gland presented by a 33 years old how it was diagnosed using cytology, histopathology and managed by surgical excision have been described.
Submandibular Gland Carcinoma ex Pleomorphic Adenoma
Acta Cytologica, 1998
Carcinoma ex pleomorphic adenoma is a rare neoplasm of the salivary gland. This lesion, also known as malignant mixed tumor, occurs when a malignant tumor arises in the epithelial component of a pleomorphic adenoma. Reports of fine needle aspiration biopsy (FNAB) diagnosis of malignant mixed tumors are rare and have been limited to cases arising in the parotid. Cytologic features and diagnostic pitfalls of this uncommon neoplasm are presented. A 75-year-old male presented with a nontender submandibular mass. The lesion had been present 12 months, with a recent increase in size. FNAB was performed, and the smears revealed a mixture of benign and malignant areas. The benign portion of the smears showed findings typical of pleomorphic adenoma. The malignant area showed large cells occurring singly and in groups. The malignant cells contained pleomorphic nuclei with irregular nuclear membranes and prominent macronucleoli; cytologically, they resembled cells from a poorly differentiated adenocarcinoma. We present the first case of carcinoma ex pleomorphic adenoma of the submandibular gland correctly diagnosed by FNAB. This rare salivary gland malignancy can be accurately diagnosed on FNAB if strict criteria are applied.

The accessory submandibular gland is a rare anatomic variant and the incidence of pathology reported within an accessory submandibular gland is even rarer. This report describes the case of a 22-year-old woman who presented with a slowly enlarging mass in the submandibular triangle, which on ultrasound examination suggested that it was close to, but not arising from, the submandibular gland. Fine-needle aspiration cytology was consistent with a pleomorphic adenoma. At surgery, the tumor was found to be entirely separate from the submandibular gland. This case presents an extremely rare occurrence of an accessory submandibular gland and, to the authors' knowledge, is the first report of a pleomorphic adenoma occurring within an accessory submandibular gland.

Submandibular gland pleomorphic adenoma in a seven-year-old child: a case report
Kulak burun bogaz ihtisas dergisi : KBB = Journal of ear, nose, and throat, 2010
Salivary gland neoplasms are rare in the pediatric age group. Pleomorphic adenomas in the submandibular gland are rarer. In this article, we present a seven-year-old female with a slowly growing mass in her right submandibular area. The firm, mobile and painless mass was about 2x3 cm in size and with bimanual palpation it was indiscriminated from the submandibular gland. Magnetic resonance imaging with contrast revealed a heterogeneous and minimally lobulated mass within the submandibular gland with clearly defined borders. Fine needle aspiration biopsy revealed a diagnosis of pleomorphic adenoma and we performed right submandibular gland excision under general anesthesia. The histopathological diagnosis was pleomorphic adenoma with sparse mitotic figures that may be interpreted as having a potential of malignant transformation. This patient who was followed up for one year without any complication is to our knowledge the youngest case cited in the English-language literature.
Pleomorphic Adenoma of the Submandibular Gland in Children: Case Report and Review of the Literature
B-ENT, 2023
An 8-year-old girl was introduced to our department due to the presence of a left painless submandibular mass. The mass had been initially noticed at 7 years of age. Preoperative imaging showed the mass to have originated from the left submandibular gland. The mass was removed with a part of submandibular gland attached to it. The pathologic findings showed the mass to be pleomorphic adenoma without any malignant components. The postoperative clinical course was uneventful. During the 1-year follow-up period, no recurrence was noticed. In addition to the clinical report of our case, we reviewed the pertinent Japanese literature to clarify the clinical features of this disease in children.
