Glomus tumor of the kidney

A 41‐year‐old man was diagnosed with a glomus tumor of the kidney, which was incidentally found by ultrasonography. Partial nephrectomy revealed a 10‐mm encapsulated mass. We diagnosed it as a glomus tumor using morphological and immunohistochemical stains.     

Glomus tumor of digital nerve: case report

Glomus tumors consist of modified perivascular, smooth muscle involved in thermoregulatory activity of digital blood flow. Digits, especially in the subungual region, are often affected. These tumors only rarely arise in peripheral nerves; digital nerve involvement is exceptional. We describe a glomus tumor occurring in the digital nerve at the level of the distal phalanx.     

Glomus jugulare tumor: tumor control and complications after stereotactic radiosurgery

BACKGROUND: We evaluated toxicity and long-term efficacy of stereotactic radiosurgery in patients with symptomatic or progressive glomus jugulare tumors. METHODS: Twenty-five consecutive patients (age, 30-88 years; 17 women, 8 men) who underwent stereotactic radiosurgery with the Leksell Gamma Knife (dose, 12-18 Gy) were prospectively followed. MRI and clinical examinations were performed at 6 months and 1, 2, and 3 years, and then every 2 years. RESULTS: None of the tumors increased in size, 17 were stable, and 8 decreased (median imaging follow-up, 35 months; range, 10-113 months). Symptoms subsided in 15 patients (60%); vertigo occurred in 1, but balance improved with vestibular training (median clinical follow-up, 37 months; range, 11-118 months). No other new or progressive neuropathy of cranial nerves V-XII developed. CONCLUSIONS: Stereotactic radiosurgery can achieve excellent tumor control with low risk of morbidity in the treatment of glomus jugulare tumors. The lower cranial nerves can safely tolerate a radiosurgical dose of 12 to 18 Gy.     

Glomus tumor of the glans penis

Glomus tumors of the penis are extremely rare. We report a patient with a solitary glomus tumor involving the penis. A 19-year-old man presented with a complaint of a recurrent painful penile mass. Resection of the lesion was performed. The pathologic diagnosis was glomus tumor of the glans penis. This case emphasizes the need for complete extirpation of the glomus tumor to avoid additional surgery.     

Glomus tumor of glans penis

Glomus tumor is an infrequent skin lesion and a rare lesion on the male genitalia. This is the second reported case of this lesion on the penis.     

儿童阴茎原始神经外胚层肿瘤/尤文氏瘤1例并文献复习

目的:探讨原发于阴茎的原始神经外胚层肿瘤/尤文氏瘤(PNET/Ewing's sarcoma)的临床表现、病理特点、治疗方法。方法:分析本院收治的1例5岁患儿原发于阴茎的PNET/EWS患者的病例资料进行文献复习。结果:病理表现为小圆细胞恶性肿瘤,免疫组化结果显示CD99(+),分子生物学检查:EWS荧光原位杂交可见易位,符合原始神经外胚层肿瘤/尤文氏肉瘤诊断,该患者经过病理确诊为阴茎PNET/EWS,经45周化疗和局部放疗,瘤灶缩小。目前停药3个月。结论:原发阴茎PNET/EWS极罕见,临床症状无特异性,以阴茎增大伴疼痛为主,免疫组化及分子生物学检查有助于对PNET/EWS的确诊。

Successful penile reconstruction after multimodal therapy in patients with primitive neuroectodermal tumor originating from the penis

We herein present an extremely rare case of primitive neuroectodermal tumor originating in the penis. A 16‐year‐old male adolescent presented with painful penile swelling. Pathological, immunohistochemical and cytogenetical examinations of the specimens obtained from total penectomy confirmed the diagnosis of primitive neuroectodermal tumor. After total penectomy, the patient received adjuvant chemotherapy with ifosfamide‐based regimen for 48 weeks. As a series of therapies, the patient underwent penile reconstruction surgery after completing adjuvant chemotherapy. The patient has not shown any evidence of recurrence for the 7 years after penile reconstruction surgery, and voiding function is completely normal. A favorable outcome was observed by multimodal therapy including aggressive resection for local control, intensive adjuvant chemotherapy, and penile reconstruction with cosmetic and functional success. Similar therapeutic approaches might be selected for children with primary malignant tumors of the penis.     

Glomus Tumor in a Segmental Bronchus: A Case Report

Glomus tumors originate from a neuroarterial structure called the glomus body, and grow mostly in soft tissue. It is rare for glomus tumors to develop in the respiratory system. The patient of the present case had an abnormal shadow in the right lung on chest X-ray, and computed tomography (CT) findings displayed a lung tumor in the right S6. Bronchoscopy was performed for the diagnosis of the lung tumor, and a polypoid bronchial tumor was unexpectedly found to occupy the right B3. The bronchial tumor was diagnosed as a glomus tumor, and the lung tumor was diagnosed as an adenocarcinoma. The bronchial glomus tumor was cauterized by argon plasma coagulation (APC). Three weeks after the cauterization by APC, the right lower lobectomy was performed for the treatment of the lung adenocarcinoma. The patient has remained disease free for 2 years.     

Glomus tumor of the stomach

A case of glomus tumor of the stomach, found 7 cm oral to the pylorus of a 23-year-old man was reported.     

Glomus tumor of the mesocolon

Glomus tumors are rare distinctive benign neoplasms, which arise from modified smooth muscle cells of the normal glomus body and are most commonly located in the subungual region of the finger. Intraabdominal locations are relatively rare. We report a case of glomus tumor of the mesocolon in a 10-year-old girl. Surgical exploration showed a lesion in the transverse mesocolon, which was excised. Histopathology showed it to be a glomus tumor of the mesocolon.     

A gase report of glomus tumor of the stomach

A case of glomus tumor of the stomach and a brief review of the literature are reported. As the neoplasma may be benign, extensive surgery should be avoided in the absence of a precise diagnosis.     

左小腿多发性血管球瘤1例

<正>患者,女,51岁,以"左小腿疼痛原因待查,血管球瘤?"收入院。家族中无类似病史者。患者1996年7月无明显诱因出现左小腿内侧及膝关节外侧剧烈疼痛,疼痛为不定期发作,发作时疼痛难忍,在外院行手术治疗后疼痛缓解;术后病理检查结果为:血管球瘤。1998年5月再次出现相同部位的剧烈疼痛,在另一医院手术后疼痛消失;术后病理检查结果为:血管球瘤。2006年又出现相同部位的剧烈疼痛,疼痛发作时,杜冷丁注     

阴茎巨型尖锐湿疣的诊断与治疗(附5例报告)

目的：探讨阴茎巨型尖锐湿疣的诊断及治疗方法。方法：回顾性分析5例阴茎巨型尖锐湿疣的诊断与治疗的临床资料，4例在抗感染3～7天后行病变组织局部切除及电灼；1例阴茎海绵体破坏严重，行阴茎部分切除术．术后以α2干扰素10^6IU每周3次进行全身治疗，连用3周。结果：随访3个月～2年，3例局部无复发，阴茎背侧皮肤有瘢痕增生，性功能正常；1例术后3个月在其他部位有复发，用疣司脱外涂后痊愈；1例4个月即有复发，后失访。结论：阴茎巨型尖锐湿疣的外观上与鳞癌难以鉴别，应取多处活检，生物学行为有潜在恶性的可能。治疗应根据病理情况及病变是否浸润Buck筋膜而决定，阴茎部分切除术是可行的治疗方法。
