Cystic Schwannoma

Introduction: Schwannoma is the most common tumor of peripheral nerves. They are usually solitary, encapsulated, homogenous slow growing masses, sometimes associated with pain and paresthesia.We present a case of schwannoma in an unusual location. Case presentation: A 16 year old boy presented to surgical OPD with a slow growing left popliteal swelling for 6 months and neuralgia for 1 month. The swelling decreasing on knee exion. Based on clinical suspicion patient was operated for popliteal cyst. Intraoperatively there was close association with nerve and it was difcult to dissect from nerve. So it was thought of being a nerve tumor. Surgical excision was done. Histopathological examination revealed it to be Cystic Schwannoma. Discussion: Schwannoma is the most common benign neoplasm of peripheral nerves. Cystic degeneration and repeated hemorrhages (10%) can occur sometimes. There are two types of tissues in Schwannoma – Antoni A and Antoni B.Schwannoma varies from 2-20 cm in diameter. It is not localized to any specic area; it can occur anywhere along peripheral nervous system in neck, mediastinum, retroperitoneum, pelvis, upper extremities. It is extremely unusual in lower limb of which tibial nerve is uncommon site. Conclusion: Diagnosis of schwannoma originating from lower extremity peripheral nerves may be delayed because it can be misdiagnosed as Baker's Cyst or the symptoms of the patient can be thought as a result of lumbar disc herniation.Thorough clinical examination and investigations, conrms the diagnosis, as management is different for both.

Schwannoma is a tumor which has neuroectoderm origins, is hard, well-circumscribed, encapsulated, and slow growing benign cranial tumor, and may autonomously grow out of the nerve sheath of peripheral nerves. It is mostly seen in the head and neck region. In the paranasal sinus and nose areas, it is seen at a rate of 4%. The diagnosis is mostly made after histopathological examination. In this paper, a Schwannoma case observed in the nasopharyngeal region was presented in a 20-year-old female who had complaints of sleeping with open mouth, snoring, foreign body feeling in throat, and swallowing difficulties. The tumor was extracted via transoral approach. No recurrence was observed during follow-up over the next year. This case presentation is presented for the first time in the literature in English.

Introduction. Osteomas are a slow growing benign neoplasm of unknown etiology very rarely involving the temporal bone. They develop in the external auditory canal on squamous sections, in the mastoid, middle and inner ear. By bone composition they are divided into spongious (osteoma spongiosum) and compact osteomas (osteoma eburnum); by growth direction, into outward-growing (exosteoma) and in inwardgrowing (endosteoma); into unilateral and bilateral; by size, into small and gigantic; by surface structure, into smooth and multilobular; by number, into solitary and multiple; into symmetrical and asymmetrical. The symptoms of intracanalicular osteomas are the result of auditory canal obstruction. Diagnosis is made based on case history, clinical examination, audiological processing and radiography (temporal bone CT scan), and confirmed by histopathological examination of the bone. In terms of differential diagnosis, they must be distinguished from exostoses, bone tissue proliferation and osteoid osteomata. The progress of the disease is prolonged, as they are slow growing, asymptomatic and benign tumours. Therapy is surgical only. Case Outline. The report presents the case of a 70-year old patient with the osteoma of the right external auditory canal. In our patient, the osteoma arose in the auditory canal, the most frequent localization; it was unilateral, solitary, multilobular and compact. It was discovered accidentally, during otoscopic examination. The clinical diagnosis was confirmed by CT scan of the temporal bone. We applied surgical therapy by retroauricular approach. The removed bone change was about 12 mm high, 13-14 mm deep and about 8 mm wide. Histopathological findings confirmed osteoma. Conclusion. Due to their slow growth, the rate of auditory canal osteomas develop asymptomatically for a long time without the characteristic clinical features. In most cases, they are discovered accidentally during otoscopic or radiographic examination. The method of choice in diagnosis is temporal bone CT scan. Therapy is surgical.

BACKGROUND: Lymphoepithelial cysts, which are benign and slow-growing tumours, usually involve the head and neck regions. Benign lymphoepithelial cysts (BLECs) are the most common cause of parotid swelling in human immunodeficiency virus (HIV)-positive patients and are less common in immunocompetent patients. CASE PRESENTATION: Here, we present two cases of immunocompetent patients with long-standing, progressively enlarging parotid swelling. Postoperative histopathological examination of these patients revealed features of BLEC. CONCLUSION: Wide surgical excision is the gold standard for treatment and recurrences is rare. These cases are of particular interest because of the rarity of BLEC in HIV-negative patients and highlight an important differential diagnosis of parotid swelling.

Schwannomas are the most common tumor of peripheral nerves. It comprises 1 to 2% of total thoracic tumor. Posterior mediastinum is the most common site in thorax. Hereby we are reporting two cases of schwannoma with different sites of origin. The classical presentation of schwannoma is an asymptomatic mass found on chest radiograph. This tumor is usually benign and slow growing. Imaging followed by histopathological examination is key to the diagnosis of this neoplasm. Resection of tumor cures the disease.

ABSTRACT Neurofibroma is a benign neoplasm derived from peripheral nerves. Most of these are associated with neurofibromatosis but may also occur as solitary lesions. When found in the neck, they are often located in the soft tissues. They are slow-growing masses, often asymptomatic and have been found most commonly in the oral cavity. We report a case of neurofibroma involving two separate and unusual sites of face, which are subcutaneous tissues of the cheek and dorsum of nose, and present a brief review of literature.

Fibrolipoma is a benign neoplasm characterized by the presence of mature adipose cells separated by broad bands of dense fibrous connective tissue. This pathology is a microscopic variant of lipoma and can affect any part of the body. However, its occurrence in the oral cavity is uncommon. It is usually a smooth-surface lesion, asymptomatic, slow-growing, pedicled, asymptomatic, yellowish or pinkish color when deeper, soft on palpation, occurring mainly in the jugal mucosa. Thus, the aim of this paper is to describe the main clinical, histopathological and treatment characteristics of a clinical case of fibrolipoma. A 67-year-old female patient, leukoderma, had a normochromic, asymptomatic, firm palpation nodule, fibrous consistency, and smooth surface, with a time course of approximately two years, located in the left jugal mucosa. The diagnostic hypotheses were lipoma, fibroma, mucus extravasation phenomenon and giant cell fibroma. The patient underwent excisional biopsy and histopathological examination revealed the definitive diagnosis of fibrolipoma. The patient is in preservation, with no sign of relapse. It is concluded that, although fibrolipoma is a benign lesion, its growth can reach large dimensions, reinforcing the need for surgical excision. It should also emphasize the importance of histopathological examination to differentiate histopathological variations of lipoma.

Within the last few years, adrenal cortical tumors with features concordant with the diagnostic criteria attributed to oncocytomas have been reported. To date, only nine reported cases exist in the literature. This report is the tenth case presentation of a presumptively benign neoplasm of the adrenal gland with a rare differentiation. Oncocytomas are well recognized benign tumors of the thyroid, parathyroid, and salivary glands and of the kidney. Other organs also give rise to these types of tumors, however with less frequency than the former sites. The characteristics generally used to classify a tumor as an oncocytoma include the following criteria: the tumor is 1) usually a solitary circumscribed mass with no gross nor microscopic evidence of metastasis (no tissue nor vascular invasion), 2) fairly bland in terms of mitotic activity and nuclear morphology, and 3) composed of large eosinophillic cells in which the cytoplasm is packed full of mitochondria (Figure 1).

Abstract Background Comamonas kerstersii is rarely associated with infections in humans and has never been reported in animals until now. Case presentation Herein, we describe a case of urinary tract infection caused by C. kerstersii in a young goat. A seven-month-old male goat showed lethargy, generalised weakness and anorexia and in the last hours before its death, severe depression, slight abdominal distention, ruminal stasis, and sternal recumbency. Grossly, multifocal haemorrhages in different organs and tissues, subcutaneous oedema and hydrocele, serous fluid with scattered fibrin deposition on the serosa of the abdominal organs and severe pyelonephritis with multifocal renal infarction were detected. Histopathological examination confirmed severe chronic active pyelonephritis with renal infarcts, multi-organ vasculitis and thrombosis suggestive of an infectious diseases of bacterial origin. The bacterium was identified using routine methods, matrix assisted laser desorption/ionisation time-of-flight mass spectrometry (MALDI-TOF-MS), and sequencing of the gyrB gene. Conclusions To the best of our knowledge, this is the first report of C. kerstersii infection in animals (goat). Our findings support the possibility of C. kerstersii isolation from extraintestinal sites and suggest this organism as a possible cause of urinary tract infection.

Abstract Background Hidradenoma papilliferum is a rare benign neoplasm arising from apocrine glands. It occurs commonly on the anogenital region of middle-aged women. It usually presents as a slow growing, solitary asymptomatic, skin colored or red nodule less than 1 cm in diameter. Case presentation The case is a 38-year-old, white woman who presented with a painful nodule occurring within a month in the himenal region of the posterior vaginal introitus. The nodule was excisied and the histology revealed a hidradenoma papilliferum. The diagnosis and treatment of hidradenoma papilliferum is possible with surgical removal and histopathological evaluation of nodules. Conclusion When an adult woman presents with a noduler lesion in the anogenital area, sexually transmitted diseases and other benign and malignant vulvar lesions, as well as malignant transformation is very rare but,should be kept in mind; however because it has been reported and long-term clinical follow-up is suggested

Abstract Background Patients who undergo peritoneal dialysis (PD) are at risk of gut bacteria translocation leading to peritonitis when there is chronic diarrhea. Chronic diarrhea is defined as any course of diarrhea that lasts at least 4 weeks, which can be continuous or intermittent. Chronic diarrhea of any duration may cause dehydration, electrolyte imbalance, and life-threatening hypovolemic shock. In PD patients, excessive ultrafiltration from the exchanges, combined with severe gastrointestinal loss, may cause hypovolemic shock, electrolyte imbalance, and metabolic acidosis. There are multiple causes of chronic diarrhea in PD patients including infective causes, mitotic lesions, and rarely the regular and excessive use of laxatives, which is a diagnosis of exclusion. Case presentation We report a case of Melanau lady with chronic diarrhea secondary to laxative usage in a patient being treated with automated peritoneal dialysis (APD). The patient went into hypovolemic shock, but luckily did not contract peritonitis. A colonoscopy revealed brown to black discoloration of the colon, a feature suggestive of melanosis coli. A biopsy of the intestine further confirmed the diagnosis by histopathological examination. Withdrawal of laxatives and the introduction of probiotics improved the symptoms tremendously. Conclusions The chronic use of laxatives in PD patients can potentially lead to a devastating problem; thus, the management team must monitor treatment commencement appropriately.
