Non-Hodgkin's lymphoma very rarely involves the esophagus, occurring in less than 1% of patients with gastrointestinal lymphoma. A few cases of mucosa-associated lymphoid tissue (MALT) lymphoma of the esophagus have been reported in the English literature. To our knowledge, there has been no report of MALT lymphoma of the esophagus coexistent with bronchus-associated lymphoid tissue lymphoma (BALT) of the lung. This report details the radiological and clinical findings of this first concurrent case.

Benign esophageal lesions occur in various diseases. Barium studies are useful for the evaluation of mucosal surface lesions but provide little information about the extramucosal extent of disease. Computed tomography and magnetic resonance imaging, on the other hand, permit the assessment of wall thickness, mediastinal involvement, adjacent lymphadenopathy, and distant spread. In diseases such as fibrovascular polyps, duplication cysts, scleroderma, trauma, caustic esophagitis, hiatal hernia, esophageal diverticulum, achalasia, and paraesophageal varices, the findings of imaging studies are specific, obviating the need for further invasive diagnostic work-up. The advent of helical computed tomography and its volume data set allows the acquisition of multiplanar images, and magnetic resonance imaging is useful both for this and for tissue characterization. Thus, multiplanar cross-sectional imaging further extends the role of imaging modalities to the evaluation of benign esophageal lesions. Through an awareness of the multiplanar cross-sectional appearances of various benign esophageal lesions, the radiologist can play an important role in the detection, diagnosis, further diagnostic planning, and treatment of the diseases in which they occur.

A giant esophageal liposarcoma showing rapid growth over 7 months is presented in 56-year-old man. It originated from the pharyngo-esophageal junction with a short stalk, and extended downward to the distal esophagus. A barium swallow study showed a large, sausage-like intraluminal mass in the dilated esophagus. CT and MR imaging showed a heterogeneous mass with a fatty component in the esophagus. A total laryngopharyngo-esophagectomy was performed and the histological diagnosis was of a well-differentiated liposarcoma.

Primary malignant melanoma of the esophagus is exceedingly rare. The existence of primary malignant melanoma in the esophagus had been in doubt until the presence of benign melanocytes was demonstrated within the esophagus. Hematogenous and lymphatic metastases are common. The prognosis is poor even after a radical procedure due to early metastasis. We report here two cases of primary malignant melanoma of the esophagus. One is a melanotic melanoma and the other is an amelanotic melanoma.

OBJECTIVE: The aim of our study was to describe and compare the radiologic findings of esophageal leiomyomas. MATERIALS AND METHODS: The chest radiographic (n = 12), esophagographic (n = 12), CT (n = 12), and MR (n = 1) findings of surgically proven esophageal leiomyomas in 12 consecutive patients [ten men and two women aged 34 - 47 (mean, 39) years] were retrospectively reviewed. RESULTS: The tumors, surgical specimens of which ranged from 9 to 90 mm in diameter, were located in the upper (n = 1), middle (n = 5), or lower esophagus (n = 6). In ten of the 12 patients, chest radiography revealed the tumors as mediastinal masses. Esophagography showed them as eccentric, smoothly elevated filling defects in 11 patients and a multilobulated encircling filling defect in one. In 11 of the 12 patients, enhanced CT scans revealed a smooth (n = 9) or lobulated (n = 2) tumor margin, and attenuation was homogeneously low (n = 7) or iso (n = 4). In one patient, the tumor signal seen on T2-weighted MR images was slightly high. CONCLUSION: Esophageal leiomyomas, located mainly in the middle or distal esophagus, are consistently shown by esophagography to be mainly eccentrically elevated filling defects and at CT, lesions showing homogeneous low or isoattenuation are demonstrated.

The primary esophageal lymphoma is extremely rare, and shows various morphologic characteristics. Only a single case of mucosa-associated lymphoid tissue (MALT) type lymphoma confined to the esophagus has been reported in the literature. A 61-yr-old man was referred to our hospital for evaluation of an esophageal submucosal tumor (SMT) that had been detected incidentally by endoscopy. He had a history of pulmonary tuberculosis with long-term anti-tuberculosis medication 15 yr before, and also had a history of syphilis, which had been treated one year before. He had been taking a synthetic thyroid hormones for the past 10 months because of an autoimmune thyroiditis. Endoscopy showed a longitudinal round and tubular shaped smooth elevated lesion, which was covered with intact mucosa and located at the mid to distal esophagus, 31 cm to 39 cm from the incisor teeth. Endoscopic ultrasonography (EUS) showed a huge longitudinal growing intermediate- to hypo-echoic mass located in the submucosal layer with internal small, various sized honeycomb-like anechoic lesions suggesting germinal centers. Subsequently, he underwent a surgery, which confirmed the mass as a primary esophageal low-grade B-cell lymphoma of MALT type.

Mediastinal tuberculous lymphadenitis is rare in adults, and it is even rarer for dysphagia to be the presenting symptom of mediastinal tuberculous lymphadenitis. Mediastinal tuberculous lymphadenitis with esophageal symptoms has been presented as esophageal ulceration, mucosal or submucosal mass with ulceration, fistula or sinus formation, extrinsic compression, or displacement of the esophagus. An exaggerated form of extrinsic compression may be presented as a submucosal tumor, radiologically or endoscopically. A barium esophagography of a 34 year-old woman with painful dysphagia revealed a large submucosal tumor-like mass on the mid-esophagus. The symptom was spontaneously improved over a 3-week period together with reduction of the mass size. A computed tomography of the chest disclosed an enlarged subcarinal lymph node and histologic examination of the specimen obtained by thoracoscopic biopsy brought about a diagnosis of tuberculosis. We herein report a case of mediastinal tuberculosis with unusual manifestations.

OBJECTIVETo evaluate the accuracy of radiographic examination, endoscopic examination and clinical response evaluation criteria in staging for esophageal carcinoma after preoperative chemoradiation therapy(pre-CRT).

METHODSTwenty-seven patients of locally advanced esophageal squamous cell carcinoma were involved. CT scan for cervical part, chest and abdomen, and endoscopic ultrasound(EUS), electronic fibrobroncoscopic examination were used to assess the tumor for staging before pre-CRT. The tumors were re-assessed using the same methods after the completion of CRT. Response evaluation criteria in solid tumors(RECIST) was used to assess the tumor response. Surgery was carried out 3 to 6 weeks after CRT. The clinical tumor response before surgery was compared with pathological tumor response after surgery. Micrometastasis detection was carried out for paraffin embedded lymph nodes using anti-keratin monoclonal marker AE1 and AE3 by immunohistochemical(IHC) method.

RESULTSThe accuracy of CT scan in staging after pre-CRT was 40.9%(9/22) for primary tumors and 68.2%(15/22)for lymph nodes, with overall accuracy of 40.9%(9/22) for TNM staging. The accuracy of EUS in staging was 38.5%(5/13) for primary tumors and 69.2%(9/13) for lymph nodes, with overall accuracy of 38.5%(5/13)for TNM staging. While CT scan combined with EUS, the accuracy for TNM staging was 46.2%(6/13). Five cases achieved CR, 14 cases achieved PR and 8 cases achieved SD according to RECIST. Among 5 clinical CR cases, 3 cases were confirmed by pathologic examination, 1 case was diagnosed as pT(3)N(1) disease by HE stain. One case with pT(0)N(0) disease by HE stain was detected with lymph node micrometastasis by IHC. Among 5 pathological CR cases, 3 cases were diagnosed as clinical CR, 2 cases were diagnosed as clinical PR before surgery. Among 15 cases of N(0) disease by HE stain, 3 lymph nodes from 2 cases were detected with micrometastasis by IHC.

CONCLUSIONSThe current examinations(barium swallow, CT scan,EUS, endoscopy guided biopsy) and RECIST are not accurate enough to assess the tumor response for esophageal squamous cell carcinoma after pre-CRT. Surgery should be recommended for patients with clinical CR after pre-CRT.
