AN UNUSUAL PRESENTATION OF LIPOMA ON THE CHEST

Intramuscular lipoma of the chest wall is a rare finding. We present the case of a 51years male who presented to the hospital with mass on the left side of the chest which was gradually progressive in size. After re- evaluation swelling was round in shape, single with well-defined margin and rubbery consistency. Preoperative imaging HRCT thorax was done which suggested a well-defined round, hypodense, non-enhancing space occupying lesion (10.2x 8.6 x2.3cm) with volume of approximately 100ml noted in the muscle of the chest wall (pectoralis major to pectoralis minor) in the left side of the chest most likely lipoma. Histopathology revealed normal adipocytes with small eccentric nucleus.

Tumor de nervio periférico: una localización poco habitual / Peripheral nerve tumor: an unusual location

Benign tumors of peripheral nerves called Schwannomas or neurilemomas, correspond to a rare pathology, represent 5% of all tumors of the upper extremity, and affects, mainly, the ulnar nerve. The incidence of Schwannoma in the literature for the radial nerve is not clearly established given the infrequency of its presentation, there are only reports of isolated cases The following publication presents the case of a male patient with a radial nerve schwannoma. Clinically, presents increased painful volume on palpation, well delimited, of soft consistency in the distal third of the right arm of 3 years of evolution, without history of previous trauma, without irradiation, or paresthesia, with preservation of motor and sensory function of radial, median and ulnar nerve. Considering that the involvement of the radial nerve is very low frequency, a review is carried out in PubMed, in the last 10 years, there are only 9 studies, grouped in case reports and imaging studies for diagnosis.

Study Of Incidence, Occurrence, Origin, And Histological Types Of Eyelid Tumors At Tertiary Care Hospital In Ahmedabad

Background: The aim of the study was to know occurrence, incidence, and various histopathological variants of eyelid tumors.It is incidence with respect to age and to analyse the distribution of tumors in various age group at new civil Hospital, Asarwa,Ahmedabad.Materials and Methods: A total of 100 cases of eyelid tumors were analyzed retrospectively in a period from May 2008to November 2010. Cases were studied in detail about general information of the patient including age and sex and grossexamination and histological features.Result: Of 100 tumors, 56 (56%) were benign and 44 (44%) were malignant. Of 56 benign lesions, 41 were in pediatric agegroup (<18 years) and 15 were in adult patients (>18 years). The common benign lesion seen was nevi (21%) followed bysquamous papilloma (12%). The common malignant lesion seen was meibomian gland carcinoma (22%) followed by basal cellcarcinoma (12%). Distribution of tumor based on origin on descending order was epithelial origin (33%), adnexal origin (23%),melanocytic origin (22%), and mesenchymal origin (22%).Conclusion: As eyelid skin is the thinnest and most sensitive skin in our body, it is often the first area in body to show changesoccur from sun damage and aging. Skin cancer of the eyelids is relatively common and of several types. Overall, the incidenceof benign tumors (56%) was more than malignant tumors (44%) in the present study. Benign tumors were more common inadolescent and young adults. Mean age of benign tumors was 33.83 years. Malignant tumors were more common in elderly. Meanage of malignant tumors was 61.40 years. Overall, sex distribution of benign and malignant tumors is equal in both the sexes.

Clinical analysis of 35 cases of benign testicular tumors / 中国肿瘤临床

Objective: To explore the postoperative effect, prognosis, and prognostic factors for benign testicular tumors. Methods: We retrospectively analyzed the clinical data of 35 patients with benign testicular tumors between May 2004 and May 2017 from Sun Yat-sen University Cancer Center, and the patients were followed up until October 2017. Results: The mean age of the 35 patients was 18.8 (0.4-44.0) years. Among them, 14 patients (40.0%) underwent testis-sparing surgery and 21 (60.0%) underwent radical orchiecto-my, and the tumor sizes were 1.8 (0.4-4.0) cm and 2.7 (1.0-8.0) cm, respectively. All patients had been cured without obvious perioper-ative complications. Postoperative histopathological tumor types included 18 epidermal cysts, 10 mature teratomas, 4 interstitial cell tumors, and 3 adenomatoid tumors. Frozen section examination of 10 cases had been operated, and all results were consistent with paraffin pathology. No patient who underwent testis-sparing surgery showed recurrence and/or metastasis during follow-up, and their sexual function and fertility were well preserved. Conclusions: Testis-sparing surgery is reliable, and the size of the tumor determines its implementation. An intraoperative rapid frozen section examination should be performed in patients with testicular neoplasms of a benign or variable nature diagnosed before operation. Patients with benign testicular tumors should undergo testis-sparing surgery, whereas others should undergo radical orchiectomy.

Quiste óseo aneurismático sólido del raquis dorsal / Solid aneurysmal bone cyst of dorsal spine

El quiste óseo aneurismático sólido es un tumor de naturaleza neoplásica indefinida, de comportamiento benigno, crecimiento rápido y agresivo. Representa menos del 8 % de todos los quistes óseos aneurismáticos. Se presenta un caso de quiste óseo aneurismático sólido de mediastino posterior con toma espinal torácica. La ausencia de signos característicos en las pruebas de imagen y la presencia de rasgos similares al tumor de células gigantes y el osteosarcoma, hacen imprescindible la confirmación anatomopatológica para un tratamiento adecuado de la enfermedad. La exéresis quirúrgica total de la tumoración, el aporte de injerto óseo y la fijación del segmento afecto constituyen el procedimiento de elección.

The solid aneurysmal bone cyst is a malignant tumor of undefined nature, benign behavior; it has fast and aggressive growth. It represents less than 8 % of all aneurysmal bone cysts. A case of posterior mediastinum solid aneurysmal bone cyst with thoracic spinal making is presented here. The absence of characteristic signs in the imaging and the presence of similar features of giant cell tumor and osteosarcoma, make it imperative the pathologic confirmation for proper treatment of the disease. Total surgical excision of the tumor, the bone grafting and fixation segment affection are the procedures of choice.

Le kyste osseux anévrismal solide est une tumeur de nature néoplasique indéfinie, caractérisée par un comportement bénin et une croissance rapide et agressive. Il représente moins de 8 % de tous les kystes osseux anévrismaux. Un cas de kyste osseux anévrismal solide au niveau de médiastin postérieur (d’atteinte spinale thoracique) est présenté. L’absence de signes caractéristiques dans l’imagerie RM et la présence de traits similaires à la tumeur à cellules géantes et à l’ostéosarcome rendent nécessaire la confirmation anatomopathologique pour un traitement approprié de cette pathologie.

Evaluation of performance of various histological grading systems of soft tissue sarcomas and the prognosis (metastatic risk and survival rate).

Background: Histologic grade represents the most important prognostic factor for all soft tissue sarcomas and it is strongly associated with the advent of metastasis and patients survival. The main objective of this study is to test individual grading system with metastatic risk and patients survival rate (prognosis). Methods: Soft tissue sarcomas (250) were graded by FNCLCC, NCI & Mhyre Jensens grading system. Special stains & immunohistochemistry were employed whenever necessary. Results: FNCLCC system shows Grade 1 = 50 (20%), Grade 2 = 75 (30%) & Grade 3 = 125 (50%). NCI (Costa et al.) showed Grade 1 = 70 (28%) Grade 2 = 85 (34%) & Grade 3 = 95 (38%). Myhre Jensen showed Grade 1 = 84 (33%), Grade 98 (39%) & Grade 3 = 68 (27%). Undoubtedly, FNCLCC system is the best of all grading systems which is very well supported by statistical analysis in this study. Conclusions: FNCLCC grading system of soft tissue sarcomas is the best documented and tested system. This present study strongly recommends FNCLCC grading system of soft tissue sarcomas to be internationally accepted because the grading system has well defined criteria & so least possible chances of interobserver variability. The present study & few other previous studies highly recommend the mandatory use of FNCLCC grading system in histopathology report format.

Non Infantile Desmoplastic Astrocytoma: a case Report.

Desmoplastic infantile astrocytomas (DIA) are huge cerebral masses with cystic and solid components in infants with a benign course. Less than 50 cases of have been reported in the literature and most of the cases are children below 24 months. We are presenting a rare case of DIA which presented at the age of 4 years with vomiting and headache in neurosurgical OPD. He was diagnosed with a huge left temporal parietal tumor with midline shift which on histopathological examination was confirmed as DIA. Patient was operated and had good recovery and was followed up for two years.

Non-Melanocytic Benign Tumors of the Face: A Retrospective Study

BACKGROUND: Although plastic surgeons daily encounter various facial tumors in the field, reports limited on face are scarce. In our study, we want to provide basic epidemiologic data to help clinicians to decide the proper management for their patients. METHODS: We retrospectively reviewed the medical records of patients including age and gender, location and size of the tumor, histopathologic result, recurrence, type of anesthesia and any associated disorders who had undergone a surgical removal of their facial tumors and received the histopathologic report in the same institution between January 2009 and October 2012. RESULTS: One hundred eighty-nine patients with 203 non-melanocytic benign tumors were included. The most frequent site of tumors was the central subunit of the forehead, followed by the lateral subunit of the cheek and the auricular unit. Of 36 different histopathologic results, the epidermal cyst was most frequent, followed by lipoma, pilomatricoma and osteoma. Statistical analysis showed that males were dominant in the epidermal cyst and lipoma groups. While, females were dominant in the osteoma and pilomatricoma groups. No associations were found between lesions and other diseases. CONCLUSIONS: Our study is the at most specific and concentrated study on non-melanocytic benign tumors of the face. We expect the epidemiologic data of our study may help plastic surgeons who are confronted with so many facial lesions in the field to decide on the most proper management for their patients.

Rânula congênita / Congenital ranula

Rânula é um tumor benigno raro da cavidade oral, envolvendo a glândula salivar sublingual ou os ductos submandibulares. É causada por um cisto mucoso de extravasamento e, menos frequentemente, por um cisto mucoso de retenção. As rânulas congênitas ocorrem secundariamente à atresia ou falência de canalização dos ductos das glândulas salivares. Na presença de lesões císticas na cavidade oral se deve excluir, como diagnóstico diferencial, hemangioma, linfoma, tumor de glândula salivar, epignathus. Trata-se de um relato de caso de rânula congênita diagnosticado por volta de 21 semanas de gestação, através de ultrassonografia bidimensional (2D) e tridimensional (3D) para determinar a origem e evolução da lesão cística. O tratamento estabelecido foi a marsupialização no 4º dia de vida do neonato. Por tratar-se de malformação rara, com incidência estimada de 0,74% em adultos, ressaltamos a importância do diagnóstico precoce para a programação de assistência neonatal especializada.

Lipoma e lipoaspiração / Lipoma and liposuction

Lipoma é o tumor mesenquimal benigno mais comum. O tratamento de escolha é a excisão cirúrgica, que pode ocasionar cicatriz conspícua dependendo da região acometida e principalmente em indivíduos com história de má cicatrização. A lipoaspiração tumescente já foi demonstrada como um método efetivo e de baixa taxa de recidiva no tratamento destas lesões, apresentando como resultado uma menor cicatriz cirúrgica. É relatado um caso de uma paciente apresentando grande lesão tumoral de aspecto lipomatoso em que a lipoaspiração foi o método de escolha (AU)

Lipoma is the most common benign mesenchymal tumor. The treatment of choice is surgical excision, which can cause conspicuous scar depending on the affected region and especially in individuals with a history of poor healing. Tumescent liposuction has been demonstrated as an effective method with low recurrence rate in treating these lesions, resulting in a smaller surgical scar. We report a case of a female patient with a large tumor of lipomatous aspect where liposuction was the method of choice (AU)

Unusual Presentation of Acrochordon.

Objective: An acrochordon, is a small, soft, common, benign, usually pedunculated neoplasm that is found particularly in persons who are obese. Acrochordons have been reported to have an incidence of 46% in the general population. Most acrochordons vary in size from 2 to 5 mm in diameter, although larger acrochordons upto 5 cm in diameter are sometimes evident. They may occur singly or in multiples and they are most often found in intertriginous areas (e.g., axillae, neck, eyelids). We report an unusual presentation of acrochordon in a 38-year-old multipara who presented with complains of some mass in the private parts since three months. She was diagnosed to have acrochordon of the clitoris.

Mioma vaginal: reporte de un caso / Vaginal myoma: case report

Presentar un caso de mioma vaginal en una mujer de 52 años. Paciente asintomática, que acude a la consulta para control ginecológico. Se detecta una lesión en cara posterior de vaginal, sobre elevada e hiperpigmentada de aproximadamente 1 cm de diámetro, la cual fue extirpada con asa diatérmica; se envió el material para estudio histopatológico y el resultado fue leiomioma en vagina con hiperpigmentación melánica en la capa basal del epitelio. La paciente evolucionó bien

Vaginal myomas are very rare, generally asymptomatics, but could be presented with diverse symptoms regarding their localization and do not differ from their uterine counterparts. We present a clinic case of a 52 years old woman, asymptomatic, in whom a 1 cm sobreelevated, hyperpigmentated lesion was found on the posterior vaginal wall, which was removed with diathermical loop excision. Her pathological result was vaginal leiomyoma with melanical hyperpigmentation of the basal layer of the epithelium. We also present a literature revision

Intracardiac leiomyomatosis: Report of two cases.

Intravenous leiomyomatosis is an example of unusual growth patterns that is sometimes exhibited by uterine leiomyomas, characterized by smooth muscle proliferations within the uterine or pelvic veins. Extension into the heart via the inferior vena cava is even rarer and is designated as intracardiac leiomyomatosis. This is a report of two such cases that had preoperative diagnoses of a thrombus and right atrial myxoma, respectively.

Congenital Cavernous Sinus Cystic Teratoma

Teratomas represent 0.5% of all intracranial tumors. These benign tumors contain tissue representative of the three germinal layers. Most teratomas are midline tumors located predominantly in the sellar and pineal regions. The presence of a teratoma in the cavernous sinus is very rare. Congenital teratomas are also rare, especially those of a cystic nature. To our knowledge, this would be the first case report of a congenital, rapidly growing cystic teratoma within the cavernous sinus. A three-month-old boy presented with a past medical history of easy irritability and poor oral intake. A magnetic resonance image (MRI) scan of the head disclosed a large expanding cystic tumor filling the right cavernous sinus and extending into the pterygopalatine fossa through the foramen rotundum. These scans also demonstrated a small area of mixed signal intensity, the result of the different tissue types conforming to the tumor. Heterogeneous enhancement was seen after the infusion of contrast medium. However, this was a cystic tumor with a large cystic portion. Thus, a presumptive diagnosis of cystic glioma was made. With the use of a right frontotemporal approach, extradural dissection of the tumor was performed. The lesion entirely occupied the cavernous sinus, medially displacing the Gasserian ganglion and trigeminal branches (predominantly V1 and V2). The lesion was composed of different tissues, including fat, muscle and mature, brain-like tissue. The tumor was completely removed, and the pathological report confirmed the diagnosis of a mature teratoma. There was no evidence of recurrence. Despite the location of the lesion in the cavernous sinus, total removal can be achieved with the use of standard microsurgical techniques.

Application of video-assisted rigid bronchoscopy in the treatment of benign tumors of tracheobronchus / 中国微创外科杂志

Objective To evaluate the feasibility and safety of video-assisted rigid bronchoscopy in the treatment of benign tumors of tracheobronchus.Methods Seven patients with benign tumors of tracheobronchus were managed with video-assisted rigid bronchoscopic surgery in this hospital from September 2002 to April 2005.The endoscopic procedure was performed under general transvenous anesthesia and jet ventilation.The tumor was firstly frozen or electocoagulated for better bleeding control,and then was removed with a biopsy clamp by parts,with the pedicle treated with freezing,coagulation or argon plasma coagulation(APC).For tumors with a broad pedicle,after the bulk of tumor was ablated under bronchoscope,a conversion to open local resection was carried out.Results All the 7 operations was accomplished smoothly without mortality or severe morbidity.Except one patient with broad pedicle leiomyoma which was resected through thoracotomy after airway clean-up and intubation,all 6 patients with narrow pedicle tumors underwent a complete tumor removal endoscopically.Postoperative pathological reports confirmed the benign diagnosis as 2 cases of hamartoma,3 cases of leiomyoma,1 case of acidophilus granuloma,and 1 case of inflammation.Follow-up observations in the 7 patients for 3~36 months(mean,17.3 months) showed no recurrence.Conclusions Video-assisted rigid bronchoscopy in the treatment of benign tumors of tracheobronchus is safe and reliable.
