Pulmonary giant chondromatous hamartoma with multifocal evolution in an infant.

Hamartoma is the most common benign pulmonary tumor in adults, but is rarely described in the pediatric population. Giant chondromatous and progressive forms are even rarer. We report the novel case of a 13-month-old infant hospitalized for giant pulmonary chondromatous hamartoma discovered during a septic episode, rapidly progressive, with severe multifocal lesions, without clear response to several cytotoxic therapies. No predisposition syndrome was identified.

Hamartoma condromatoso de parede torácica: relato de caso / Chondromatous chest wall hamartoma: case report

"O hamartoma condromatoso (HC) é um tipo raro de tumor benigno de cartilagem que se origina nos primeiros anos de vida. Na maioria das vezes seu sítio primário é o gradil torácico e pode ou não ter sintomatologia. Suas características histológicas mostram proliferação do tecido conjuntivo cartilaginoso associado a cistos de células ósseas. É de difícil diagnóstico devido sua apresentação histológica. Neste trabalho é relatado um caso de HC e sua evolução"

"Chondromatous hamartoma (HC) is a rare type of benign cartilage tumor that originates in the first years of life. Most of the time its primary site is the thoracic bar and may or may not have symptoms. Its histological characteristics show proliferation of cartilaginous connective tissue associated with bone cell cysts. It is difficult to diagnose due to its histological presentation. This work reports a case of HC and its evolution"

Chondromatous hamartoma of cervical esophagus: a case report and literature review.

Esophageal chondromatous hamartomas are very rare tumors, characterized by proliferating hyaline cartilage cells. We described the case of a 64-year-old woman, with a progressive foreign body sensation in the laryngopharynx caused by an intraluminal pedicled mass. Transcervical esophagectomy was performed and intraoperative biopsy revealed the mass was a cervical esophageal chondromatous hamartoma. The patient's postoperative course was uneventful and she recovered well. A review of the literature was conducted, and the symptoms, locations, histopathology findings, treatment methods and follow up results of esophageal hamartoma cases were summarized. We found that pre-operative endoscopic ultrasonography-guided fine-needle aspiration (EUS-FNA) can aid in diagnosis and that aggressive surgical treatment should be recommended for cervical esophageal hamartomas.

Videothoracoscopic identification of chondromatous hamartoma of the lung.

INTRODUCTION: The main disadvantage of a videothoracoscopic procedure is the lack of touch sensation. The probability of easily finding the lesion is usually estimated according to computed tomography (CT). AIM: To find useful parameters of location of chondromatous hamartoma of the lung parenchyma in relation to its size to assess the probability of successful search via a videothoracoscopic approach only. MATERIAL AND METHODS: A group of 55 patients operated on for chondromatous hamartoma of the lung at the First Department of Surgery in Olomouc from January 2006 to June 2011 was analyzed. Initially, the tumor's longest diameter and its nearest distance to the pleural surface were measured on CT scans. Subsequently, the surgery began using the videothoracoscopic approach. A short thoracotomy with direct palpation followed when videothoracoscopy failed. RESULTS: No significant differences in age, sex and side of localization between the group with and without successful videothoracoscopic detection were found. A significant difference was found in the median size (p = 0.026) and the depth of the tumor (p < 0.0001) and in the calculated index "tumor size/depth" (p < 0.0001). Deeper analysis revealed that the parameters "depth" and "index size/depth" are considered to be good predictors but the parameter "size" is not a suitable predictor. CONCLUSIONS: The main predictors of successful videothoracoscopic detection of lung chondromatous hamartoma are considered to be the depth of the tumor in the lung parenchyma with a cut-off value ≤ 7.5 mm and the index "size/depth" with a cut-off value ≥ 1.54; the tumor size is not considered to be a good predictor.
