Lymphangiomas are benign tumors of lymphatic vessels, which can occur anywhere the lymphatics exist. The lymphangioma of the esophagus is exceedingly rare. Seven cases had reported in the world and there is no case report about the lymphangioma of the esophagus in our country. So we present one case of lymphangiomas that coexist in esophagus and sigmoid colon. This kind of case don't have been reported yet.

Lymphangioma is an uncommon, benign hamartomatous malformation that consists of dilated lymphatic channels lined by normal, single-cell lymphatic endothelia. The lymphangiomas are divided into cavernous lymphangioma, cystic hygroma, lymphangioma circumscriptum, and acquired progressive lymphangioma. Acquired lymphangioma circumscriptum usually occurs due to surgery, infection or radiotherapy, which leads to obstruction of lymphatic vessels. Clinically, the lesions appear as thick-walled, 2~5 mm translucent vesicles. Spontaneous drainage of straw-colored to milky-white fluids may occur. Herein, we report an acquired lymphangioma circumscriptum of the nipple areola without preceding causes.

We have experienced one case of lymphangioma and one case of lymphangiectasia which was diagnosed with the histopathologic studies, including immunofluorescent and electron microscopic methods. The distribution of Ig G and Ig A within the stroma was shown, particularly in the inflammatory cells. The endothelial lined lymphatic vessel consisted of interrupted basal lamina and absence of pericyte on electron microscope.

A case of Lymphangiomatosis of the skeleton and soft tissue in a 23 years old woman is presented. Lymphangiomatosis are benign tumors formed of lymphatic vessel and like hemangiomatosis are probably best thought of as harmatomatous malformation. As term imply, the endothelial space in these lesions are lymph-rather than blood containing. Bone involvement are very rare condition that affect mainly the ilium and features a largely lytic pattern, consisting of tiny elliptical radiolucents slots. Treatment and Prognosis depend on the site and extent of involvement and progression. Although irradiation may be the treatment of choice, the lesions have not been usually successfully treated.

Sclerosing lymphangitis of the penis is a rare disorder characterized by painless. firm. cord-like lesion in the coronary sulcus of the penis. Although sexual trauma may be causative factor the etiology is unknown. Histologic findings reveal hypertrophy and sclerosis of lymphatic vessel wells, and some cases show thrombus formation within dilated vessels. Most cases are self-limited and conservative management is indicated. We report two cases of sclerosing lymphangitis of the penis in a 37-year-old man and a 28-year-old man.

PURPOSE: To evaluate the pathologic effects of preoperative radiotherapy on the resectable distal rectal cancer, we analyzed the results of postoperative pathologic findings for the patients with preoperative radiotherapy and surgery. MATERIALS AND METHODS: From July 1995 to April 1996, we treated sixteen patients of resectable rectal cancer with preoperative radiation therapy and curative surgery. At diagnosis, Thomas Jefferson (TJ) system was used for the clinical stage of the patients. We treated the patients with conventional radiation therapy of 4500-5000cGy before surgery. The surgery was carried out 4 weeks after completion of radiation therapy. Modified Astler Coller (MAC) system was used for the postoperative pathologic stage. We analyzed the pathologic stages and findings according to preoperative clinical stage and compared with those of the control group in similar clinical stages. RESULTS: All patients were treated with sphincter preservation surgery after preoperative radiation therapy. Pathologic complete response (CR) was shown in 1 case (6.3%). We compared the results between preoperative radiation therapy group (Preop.RT group) and surgery only group (control group). In TJ stage II, among nine patients of Preop.RT group, 8 patients (88.9%) were in MAC stage B except 1 CR patient, but among 17 patients of control group, 11 patients (64.7%) were in MAC stage B and 6 patients (35.3%) in MAC stage C. In TJ stage III, among 7 patients of Preop.RT group, 4 patients (57.1%) were in MAC stage B and 3 patients (42.9%) in MAC stage C. Among 14 patients of control group, 4 patients (28.6%) were in MAC stage B and 10 patients (71.4%) in MAC stage C. Above results showed that postoperative pathologic stage was decreased in Preop.RT group with statistical significance (p=0.049). The postoperative pathologic findings (blood vessel invasion, lymphatic vessel invasion, perineural invasion) were decreased in the Preop.RT group compared with those of control group. But statistical significance was found only in lymphatic vessel invasion (p=0.019). CONCLUSION: The postoperative pathologic stages and adverse prognostic pathologic findings were decreased in preoperative radiation therapy group. The lymphatic vessel invasion and MAC stage C findings were abruptly decreased in preoperative radiation therapy group. The preoperative radiation therapy was found to be effective in resectable rectal cancer. The patients group in our study was very small and long term follow up was not done. Therefore, further study about this issues is needed .

Sclerosing lymphangitis of the penis is a peculiar disorder characterized by painless, firm, cord-like lesion in the coronary sulcus of the penis. Histologic findings include thickened lymphatic collecting vessels, fibrin thrombi and few inflammatory changes. The etiology is unknown, but the condition is benign and self-limited. We describe herein a 27-year-old man who had a typical painless, tender, firm, cord-like lesion in the coronary sulcus. Histologic findings disclosed a markedly thickened and fibrosed lymphatic vessel with a organizing thrombus. Whatever the cause of thrombi formation, it is prohable that the thrombi formation would be a main pathologic process, followed by the thickening of the vessel wall.

Sclerosing lymphangitis of the penis is a rare condition involving the distal lymphatics that is characterized by cord-like lesions on the shaft or coronal sulcus. Although the etiology is unknown, its association with mechanical trauma, anatomic variants, or infection has been shown. Clinically, the patient notices a painless, firm, cord-like lesion just proximal to the sulcus. Histologic study reveals hypertrophy and sclerosis of lymphatic vessel walls and, in some cases, thrombus formation within the dilated vessels. Most cases are self-limited, and conservative management is indicated, but surgical excision is warranted for persistently symptomatic lesions. We report three cases of sclerosing lymphangitis of the penis that required treatment by surgical excision.

Cystic hygroma, or cystic lymphangioma, is a true, benign, congenital rnulticystic tumor arising from sequestrations of embryonic ly mphatic iissue. Most often it occurs. At birth or early in life, and it is found most commonly in the neck, and its distribution coincides with that of the prirnitive lymph sacs. We report herein a case of huge cystic hygroma on the face and neck in a 2 month-old male infant. The swelling was softly cystic, and was partially compressible, and it was brilliantly translucent. The cystic mass contained a serous fluid. Biopsy findings showed simple endothelium-lined lymphatic vessel and loose, lace-like fibrous tissue stroma, and dilated muscle space filled with serous fluid.
