口蓋色素性母斑の2例と本邦報告例の臨床統計

Two cases of pigmented nevus of the palate are presented. The first case was an intradermal pigmented nevus in a 32-year-old male and the other a junctional pigmented nevus in a 49-year-old female. We also reviewed 31 cases reported in Japanese literatures, and the resultswere as follows: 1) Histologically, the intradermal type is the most common (68%), followed by compound (23%) and junctional types (9%). 2) Pigmented nevus develop mostly on the palate (39%), with gingiva of the mandible (32%), buccal mucosa (13%), and lip (10%), gingiva of the maxilla (6%). 3) More females than males have pigmented nevi. 4) The highest incidence is in the third and fourth decades, and almost half of the patients (55%) are in those age groups. 5) Size, given as the largest dimension of the lesion, ranged from 2mm to 40mm. More than four fifths (89%) are described as slightly raised or as raised, and the remaining lesions are flat. 6) The lesions were surgically excised, and except for our one case there are no reports of recurrence

There are many theories regarding the origin of the lateral cervical cyst, among them two main theories are mentioned. One is that the cyst arises from the embryonic branchial cleft and the other is that it originates from salivary gland epithelium enclosed in the embryonic lymphnodes. The investigators who support the former theory refer to it as the branchial cyst while the workers who support the latter refer to it as the lymphoepitherial cyst. The typical histologic feature is that the inner wall is covered with squamous epithelium and that lymphoid tissue is embedded in the outer wall. This cyst is located on the lateral side of the neck, hence it is called the lateral cervical cyst. Recently we have encountered two cases of this cyst, hence the outline of the cases will be given. CASE 1 : An 18-year-old female noticed a painless swelling on the right side of her neck two months hence. The swelling slowly increased in size and eventually she came to our clinic. Except for an egg-like diffuse swelling that fluctuated to palpation, her condition was aggravated. 15ml of yellowish liquid solution was aspirated by puncture probatoria and the cyst was diagnosed as a lateral cervical cyst. As a result the cyst was surgically removed. This case was diagnosed as a lateral cervical cyst, "BaileyI type," by operative and post operative pathological findings. CASE 2 : A 15-year-old female child noticed two walnut-like swellings on the right side of her upper neck about six months before coming to our clinic and was immediate referred to a surgeon. At surgery one cyst was removed. The cyst was diagnosed as non-mallignant. After surgery the remaining cyst grew in size and dimension. The swelling was 50mm in diameter on the center right side of the angulus mandiblae. At the first we considered the swelling as tuberculous lymphadenitis but after further examination we diagnosed the case as lateral cervical cyst and thus removed it by surgical methods. The cyst was diagnosed as a lateral cervical cyst, "Bailey II type" by operative and pathological findings
