腮腺真性囊肿系腮腺腺体内的小囊肿,临床较少见,其大小直径多在1cm或1cm以下,常因婴儿期腺体内导管先天性扩张而形成多房性囊区,如感染,内含清亮液体,可一直持续到成年期。若反复感染,则增加手术困难。现将我科所遇1例报道如下: 患者男性,49岁。6年前发现在左耳垂下方有一蚕豆大小包块,无任何不适,未进行诊治。1年前在院外就诊曾抽出少许淡黄色液体,近几月来感包块逐渐增大,略感胀痛。检查见左耳垂下方有一直径约3cm大小包块,边界不清,中等度硬,表皮无红肿,无波动感及压痛。于1986年1月5日在局麻下手术切除。术中见包块与周围组织无明显界限,切除包块直径约为2.5cm大小,有一直径1.5cm空腔,内含淡黄色液体。未见有明显包膜及囊膜。病理检查见切除包块为腮腺组织,导管排列呈囊状、腺体破坏,导管残存,间质有大量淋巴细胞浸润,并可见有肉芽肿及多核巨细胞形成。病理诊断为“腮腺真性囊肿伴肉芽形成”。术后7天切口愈合出院。随访1年半未见复发。
The parotid true cyst is a small cyst in the parotid gland gland. It is rarely seen in clinical practice. Its size and diameter are often less than 1cm or less than 1cm. It is often due to congenital dilatation of the duct in the infancy and forms a multi-atrial cyst, such as infection. With clear liquids, it can continue until adulthood. Repeated infection increases the difficulty of surgery. One case reported by our department is as follows: The patient is 49 years old. 6 years ago, it was found that there was a large bean mass under the left earlobe without any discomfort and no diagnosis or treatment. A little pale yellow liquid was taken out of the hospital a year ago. In recent months, the mass has gradually increased and it feels slightly painful. Check the left earlobe below a diameter of about 3cm mass, the border is unclear, moderate hardness, epidermis without redness, no sense of volatility and tenderness. On January 5, 1986, surgical resection was performed under local anesthesia. During the operation, there was no obvious boundary between the mass and the surrounding tissue. The resected mass had a diameter of about 2.5 cm and a cavity with a diameter of 1.5 cm containing a pale yellow liquid. No obvious capsule and capsule were observed. Pathological examination showed that the parcels were parotid glands with cystic ducts, destruction of glands, and residual ducts. There were a large number of lymphocytes infiltrating the stroma, and granuloma and multinucleated giant cells were observed. The pathological diagnosis was “sacral true cyst with granulation”. The wound was healed and discharged after 7 days. There was no recurrence in the follow-up of one and a half years.
