Venous malformation with phleboliths is uncommon cause of unilateral parotid swelling. The clinical and radiographic appearance of venous malformation with phleboliths may masquerade as sialolithiasis. A 49-year-old female complained about unilateral parotid swelling for 6 years. Preoperative evaluation including computed tomography and sonography showed the suspicion of venous malformation with phleboliths. Superficial parotidectomy was performed. Pathological examination confirmed that the mass was venous malformation with phleboliths combined with sialolith in the parotid gland. We present the case of unilateral parotid swelling caused by a venous malformation combined with sialolithiasis.

Primary malignant lymphoma of the parotid gland is extremely rare entity and seldom described in the literature. Extranodal marginal zone B-cell lymphoma of mucosa associated lymphoid tissue(MALT lymphoma) is a relatively indolent disease and tents to remain localized for prolonged period of time. MALT lymphoma can be diagnosed after immunohistopathological study. Clinically, most MALT lymphomas are localized at the time of diagnosis and may be curable with local therapy alone, either surgery or radiotherapy. We present a case of MALT lymphoma in both parotid glands of patient who detected a left infraauricular huge mass as a first symptom and underwent surgical excision and immediate reconstruction using sternocleidomastoid myocutaneous flap.

Rhabdomyosarcoma is the most common sarcoma in children less than 15 years of age. Two major histological subtypes are embryonal and alveolar. Embryonal rhabdomyosarcoma is diagnosed by immunopathology and treatments require coordinated management plans that include surgery, chemotherapy, and usually radiotherapy. 8-month-old male infant visited with swelling in left parotid area. Computed tomography scan showed a heterogeneous mass in the left parotid area and the result of fine-needle aspiration cytology was suspicious malignancy. Left total parotidectomy was performed and CSF leakage was noted and repaired. Confirmed by positive reactions to desmin and myogenin, the diagnosis was embryonal rhabdomyosarcoma. On postoperative brain MRI, extension along the meninges was noted and for treatment, chemotherapy and gamma knife radiosurgery were done. Five years after initial surgical resection(3 years and 10 months after completion of chemotherapy and gamma knife radiosurgery), the child did not show any evidence of local recurrence or distant metastasis.

Dermoid cysts are developmental anomalies that represent the simplest form of teratoma. They are the result of the sequestration of the skin along the lines of embryonic closure. These cysts of the head and neck are uncommon and account for 7% of all dermoid cysts. They are predominantly found in the orbit, floor of mouth, and nose. As a dermoid cyst of the parotid gland is extremely rare, it is often misdiagnosed preoperatively. By way of imaging modalities such as computed tomography, MRI and ultrasongraphy along with FNAB, it can be differentiated from many other cystic lesions of the parotid gland. We report a case of dermoid cyst of the parotid gland which masqueraded as lipoma before complete surgical excision.

Neck mass is a common manifestation from head and neck malignancy, most of which come from mucosal squamous cell carcinomas in the upper aero-digestive tract. However, once aspiration cytology suggests atypical malignant cells in the neck mass rather than metastatic squamous cell carcinomas, it is confusing to decide the adequate diagnostic work-ups and treatment planning. Here, we report a 29-year-old woman presenting with a growing neck mass mimicking malignancy of unknown origin, which was finally diagnosed as primary lymphoepithelial carcinoma in the parotid gland with multiple metastases to the lymph nodes. The patient underwent comprehensive neck dissection and total parotidectomy and the adjuvant radiation treatment was given. Our report highlight that the primary salivary gland cancer should be considered as the potential tumor origin in case of malignancy of unknown origin in the head and neck region and neck mass suggestive of atypical carcinomas.

이하선에 생기는 전이성 다형태 선종은 매우 드문 질환으로서 조직학적으로는 양성이나 임상적으로는 전이를 일으키는 논쟁의 여지가 많은 병변이다. 저자들은 이하선의 다형성 선종으로 절제술을 경험한 57세 남자에게서, 4년 후에 흉막과 우측 폐, 종격동, 심낭, 늑간근의 다발성 전이를 진단하여 전이암 절제술을 경험하였기에 보고하고자 한다.

There are various types of malignancy in eyelid, such as squamous cell carcinoma, melanoma, and sarcoma. These malignant tumors have potential of metastasis by regional lymph node drainage. The lymph node around parotid gland has been known as a common site of regional lymph node metastasis. The rarity of malignant tumors in the periorbital area makes it difficult to determine the optimal extent of treatment. We report a case of parotid metastasis after eyelid cancer operation in a 60-year-old man.

Pleomorphic adenomas is the most common tumor of parotid gland and usually located and confined in superficial lobe of parotid gland. Computed tomography (CT) is commonly used to initially evaluate salivary gland lesion, but contrast-enhanced CT may sometimes fail to reveal lesions in spite of a high clinical suspicion. For this reason, ultrasonography (US) can be used as the first-line image work-up in some cases of parotid gland benign tumors. We experienced a case of a 60-year-old woman without underlying disease presenting a palpable parotid mass in which the initial CT examination was reported as 'no obvious mass detected'. However, the lesion was revealed in US and histologically confirmed as pleomorphic adenoma. The patient underwent superficial parotidectomy through modified facelift incision. To the best of our knowledge, this is the first report of invisible major salivary gland tumor on CT in the Korean literature.

Mammary analogue secretory carcinoma (MASC) has histologic similarities to not only acinic cell carcinoma but also other low grade cystadenocarcinoma, and has similar features to breast secretory carcinoma. MASC was not described through the existing classification system previously. But, MASC was distinguished from other salivary gland tumors by Skalova et al. in 2010, MASC has ets variant gene 6-neurotrophic tyrosine kinase, receptor, type 3 (ETV6-NTRK3) translocation. So far, there are 4 cases of MASC recognized in the head and neck region in Korea. One of the four is a tumor from the submandibular gland, and the other three are of the parotid gland. In this case report, we report a 40-year-old man with a MASC of the parotid gland, who presented with right infra-auricular mass.
