Successful treatment of bronchial mucoepidermoid carcinoma in an 11-year-old boy by bronchoplasty: Report of a case

We report herein the rare case of an 11-year-old boy in whom mucoepidermoid carcinoma of the right upper lobe bronchus was successfully treated by bronchoplasty. The patient underwent bronchoscopy to investigate the cause of relapsing respiratory infections over the past 2 years, which revealed a tumor at the orifice of the right upper lobe bronchus. Thus, a right upper sleeve lobectomy was effectively carried out, preserving right pulmonary function. The tumor was observed to partially invade the bronchial wall, but not the lung parenchyma. Histological examination confirmed a diagnosis of mucoepidermoid carcinoma, classified as grade 2 by Conlan's classification. The patient has been well and free of recurrence for 3 years postoperatively.     

Inflammatory pseudotumor of the spleen: Report of a case

A case of an inflammatory pseudotumor arising in the spleen of a 60-year-old Japanese male is described herein. This benign lesion is extremely rare, with only 12 cases, including our own, having been reported in the world literature. We preoperatively diagnosed the splenic tumor as a metastasis, due to the coexistance of advanced stage carcinoma in the sigmoid colon. However, after splenectomy, histopathological examination of the mass revealed aninflammatory process. Inflammatory pseudotumors often pose diagnostic difficulties because the clinical and radiologic findings are suggestive of malignancy. The clinical and pathological features of cases previously reported are reviewed following the presentation of this case.

Endobronchial leiomyoma: Report of a case treated by bronchoplasty and a review of the literature

Endobronchial leiomyoma is exteemely rare. Most endobronchial leiomyomas reported in the literature have been resected by either lobectomy or pneumonectomy. We herein report a case treated by sleeve bronchoplasty without pulmonary resection. A 42-year-old woman was admitted to our hospital complaining of hemoptysis. Bronchoscopy revealed a lobulated tumor arising from the medial wall of the right main stem bronchus. A sleeve resection of the right main bronchus including the tumor and end-to-end anastomosis was performed. The histological diagnosis of the resected specimen was leiomyoma with no evidence of malignancy. The importance of early diagnosis and appropriate surgical treatment to preserve pulmonary function are emphasized. Similar cases of an endobronchial type of pulmonary leiomyoma reported in the literature are also reviewed.     

儿童输尿管炎性假瘤1例报告并文献复习

目的：探讨输尿管炎性假瘤(1nflammatory pseudotumor，IPT)的临床特点，提高其诊治水平。方法：报告1例9岁男性输尿管IPT患者，并复习文献就相关问题予以讨论。结果：术后患者恢复良好，痊愈出院。病理检查证实为输尿管IPT。结论：IPT指组织炎性增生形成的肿瘤样团块，根据症状、体征及影像学检查结果难与恶性肿瘤相鉴别，其确诊有赖于病理学检查。输尿管IPT治疗大多仍需行外科手术，并在治疗后进行随访。     

肝脏炎性假瘤的临床病理要点

目的 探讨肝脏炎性假瘤的临床病理要点。方法 对我院从1994年6月至2000年4月病理证实为肝脏炎性假瘤的穿刺及手术切除的37例标本的临床病理要点进行分析和讨论。结果 肝脏炎性假瘤在临床上可以无症状，在这37例中无症状的有25例(67．6％)。病理诊断上也有本身特殊的表现。结论 肝脏炎性假瘤极为少见，临床上常与其它的肿瘤相混淆，确诊只能依靠病理检查，因此其临床病理要点对于临床及病理医生来说都具有重要价值。

目的:提高对肾脏炎性假瘤(RIP)的认识及诊治水平。方法:回顾性分析我院近年来诊治的9例RIP患者的临床资料,并结合文献复习探讨RIP的诊治方法。结果:9例患者中,5例误诊为肾癌,行肾切除术;1例误诊为肾盂癌,行肾、输尿管、膀胱切除术;3例经穿刺病理活检证实为炎症,行抗炎治疗后痊愈。密切随访1~6年,6例行切除术的患者中,3例未见肿瘤复发;3例确诊的患者也未见肿瘤复发。结论:RIP诊断困难,临床上极易误诊,细针穿刺活检是其确诊的主要依据。     

Successful treatment of bronchial mucoepidermoid carcinoma by bronchoplasty

A 63-year-old man who was pointed out abnormal shadow on chest X-ray admitted to our hospital. Chest computed tomography (CT) showed a tumor originated from right upper bronchus and grew into right main bronchus. The tumor was diagnosed as mucoepidermoid carcinoma by bronchoscopic biopsy. Fluorodeoxyglucose positron emission tomography (FDG-PET) showed abnormal uptake localized at the tumor. The standardized uptake values of the tumor 60 minutes after injection were 2.86, and 120 minutes after injection, it increased to 3.97. Right upper lobectomy with bronchoplasty by deep wedge resection of right main bronchus at the orifice of right upper bronchus and lymphadenectomy was performed. Pathological diagnosis was high-grade mucoepidermoid carcinoma without lymph nodes metastasis which was compatible with FDG-PET. Postoperative course was uneventful.     

Inflammatory pseudotumor of the breast: case report and literature review

Inflammatory pseudotumor (IP) is a benign lesion that can affect any tissue in the body and which may be confused clinically and in imaging for malignancy. Despite the widespread performance of breast biopsy, the finding of inflammatory pseudotumor of the breast is exceedingly rare. Excision of the tumor is the treatment of choice, but there is a relatively high rate of recurrence. The aim of this report is to describe the clinical, imaging, and pathologic features in a case of breast IP, the first reported case in a postpartum woman still nursing her infant.     

Inflammatory pseudotumor of the spleen: Report of a case

A case of a 45-year-old Japanese man with a splenic inflammatory pseudotumor is described. This benign lesion is rarely reported in the world literature. We preoperatively could not rule out the possibility of a malignant neoplasm, due to the fact that the tumor had grown in size after a 2-year observation. However, after performing a splenectomy, a histological examination of the mass revealed an inflammatory process. Inflammatory pseudotumors often pose diagnostic difficulties because the clinical and radiological findings tend to suggest a malignancy. The clinical and pathological features of such previously reported cases are also reviewed. Received: August 9, 1999 / Accepted: March 24, 2000

Subscapularis tendon rupture in an 8-year-old boy: a case report

Since falling off a motorcycle 2 years earlier, an 8-year-old, right-hand-dominant boy reported anterior shoulder pain and weakness. After being evaluated by his family physician and completing a course of physical therapy with no symptomatic improvement, he was seen at our institution. Physical examination was remarkable for diminished strength with internal rotation (4/5). In addition, bellypress and lift-off tests were positive, suggesting a lesion of the subscapularis. Magnetic resonance imaging of the shoulder showed a full-thickness subscapularis tendon tear and a supraspinatus tendon signal that could have represented a partial-thickness tear vs supraspinatus tendinosis. The patient underwent right shoulder diagnostic arthroscopy with debridement of a partial-thickness articular-sided tear of the supraspinatus tendon followed by open repair of the subscapularis tendon rupture. This case illustrates a traumatic subscapularis tendon injury that is rare in this age group. A few other traumatic subscapularis injuries have been reported in children, but they all demonstrated bony avulsion of the lesser tuberosity.     

Lipoblastoma in a 14-year-old boy: Report of a case

Lipoblastoma is a rare benign neoplasm of embryonal fat which occurs primarily in infants and young children. Since 1958, lipoblastoma has been recognized as an entity distinct from other benign or malignant tumors of the adipose tissue. This tumor presents in two forms: as a localized, well-circumscribed lesion known as lipoblastoma, or as a multicentric type of lesion known as lipoblastomatosis. The oldest patient documented in the English literature was 8 years of age; however, we report herein the case of a 14-year-old boy in whom a lesion excised from the left thigh was histopathologically confirmed to be a lipoblastoma.

Pleomorphic adenoma of the trachea in an 8-year-old boy: a case report

We report a case of pleomorphic adenoma of the trachea in an 8-year-old boy who required emergency surgery for severe respiratory distress. Chest computed tomographic scan and bronchoscopy showed a relatively large mass in distal trachea and right main bronchus and destruction of the lung parenchyma. The patient was subjected to right carinal resection, pneumonectomy, and pericardial patch tracheoplasty for reconstruction of the trachea. Histopathological examination and immunohistochemical staining of tumor specimens were compatible with pleomorphic adenoma. Postoperative follow-up of this patient for a period of 6 months showed satisfactory results with no complications or tumor recurrence. We present not only a very rare benign tracheal tumor in children but also demonstrate successful usage of a free pericardial patch for tracheal reconstruction, although direct anastomosis failed to provide an adequate anastomotic lumen.     

Inflammatory pseudotumor of the bladder in neonates.

Inflammatory pseudotumors of the bladder are rare in children. We describe a 7-day-old male neonate with inflammatory pseudotumor of the bladder. He presented with a 3-day history of macroscopic hematuria. Ultrasonography, computed tomography and cystoscopy showed an intravesical mass arising from the right lateral wall. Pathologic findings obtained by open excision revealed that the tumor had spindle-shaped cells without significant atypia infiltrating into submucosal fibrous tissue. There has been no evidence of recurrent tumor 12 months post-operatively. To our knowledge our case is the first presentation in a neonate among the reported pediatric cases.
