Five puppies were presented to the Alfort National Veterinary School for a rapidly expanding, well-demarcated, subcutaneous cervical mass of a few days’ duration. In all cases, previous trauma was reported. Fine-needle aspiration of the mass in each case revealed a serosanguineous fluid containing mainly erythrocytes, with a total protein concentration ranging from 3.5 to 5.2 g/dL. Coagulation tests failed to reveal any coagulation disorder. En-bloc surgical removal of the fluid-filled mass associated with short-term postoperative drainage was curative in all cases. Histopathological examination of the mass revealed encapsulated hematoma. The disease resembles chronic expanding hematoma in humans.

Shear wave elastography (SWE) can be useful to discriminate between malignant and benign mammary tumors. In dogs with elevated progesterone levels compared to the baseline and fast-growing tumors, treatment with the use of aglepristone allows for tumor size reduction, which facilitates surgery. This study aimed to evaluate the influence of the preoperative treatment of benign mammary tumors (BMTs), performed with the use of aglepristone, on the density of the tumor tissue measured by SWE. Twelve female dogs with diagnosed BMTs and increased levels of progesterone were treated with aglepristone (Alizine, Virbac, France) at 10 mg/kg s.c. (Subcutaneous injection). twice, with a 24 h interval. The density of the tumor was evaluated by SWE before and after the treatment. The type of tumor was evaluated by fine needle aspiration cytology before treatment, and a histopathological examination was made after surgical removal, performed after the aglepristone treatment. In all the cases, a significant reduction in the mammary tumor’s size was observed following treatment, with no influence on the density of the tumor’s tissue measured by SWE. Similar studies on malignant mammary tumors are warranted to verify if in these cases, density will also be a constant parameter that is not dependent on the tumor size.

Background: Capillary hemangiomas are benign vascular lesions commonly seen in subcutaneous tissues. The most common site of origin is from the vertebral body, and only a few cases of isolated lesions in thoracic epidural space, especially after trauma, have been reported in the literature. Case Description: We report a case of 63-year-old male with progressive bilateral lower limb weakness and exaggerated lower limb deep tendon reflexes without bowel and bladder involvement. His history revealed T7 fracture with paraparesis which was treated surgically, and implants were removed a year later. MRI showed an epidural lesion from T6-T8 extending into the right T7-8 foramen which showed hypointensity on T1, hyperintensity on T2, and homogenous enhancement in contrast images with severe cord compression. Laminectomy was done and the lesion was removed en bloc. Histopathological examination revealed it to be capillary hemangioma. The neurology came back to normal after 3 months. Conclusion: Although capillary hemangiomas are rare lesions, it has to be considered in the differential diagnosis of epidural space-occupying lesions which require early surgical removal to prevent a progressive and permanent neurological deficit.

Gastric carcinosarcoma is a rare biphasic tumor that consists of both carcinomatous and sarcomatous components. Clinical presentation and neoplastic markers are not specific for the disease. Moreover, CT scan cannot distinguish among gastric carcinoma, sarcoma or carcinosarcoma, so it is essential to perform histopathological and immunohistochemical analysis on biopsy specimens or resected tissue to ensure a correct diagnosis. A 72-year-old woman was transferred to our Department from another hospital with a diagnosis of a bleeding tumor localized on the lesser gastric curve, infiltrating the left hepatic lobe. The mass was treated as a gastric malignant mesenchymal neoplasia (gastro-intestinal stromal tumor versus sarcoma) infiltrating the liver. Owing to the bleeding, no further invasive examinations, such as fine needle aspiration biopsy, were planned. Furthermore, no neoadjuvant chemotherapy could be administered before surgery due to persistent anaemia. The scheduled surgical procedure was an atypical gastric resection with “en bloc” hepatic resection. This operation included upper polar and lesser curve resection, with tubulization of the stomach along the greater curve, as well as left lateral hepatic sectionectomy. Histopathological examination and immunohistochemical staining confirmed the diagnosis of gastric carcinosarcoma. This is first report of gastric carcinosarcoma with local liver infiltration, treated with surgical resection.

Background: Spinal extradural arachnoid cyst is an uncommon, expanding lesion which may communicate with the subarachnoid space, The etiology still remains unclear, but the most accepted explanation is the existence of areas of weakness in the spinal dura , Spinal arachnoid cysts are usually in the thoracic spine, and they may cause symptoms due to spinal cord compression. Case Presentation: Patient is a 54-years-old female who presented with progressive back pain and motor deficit, Magnetic resonance imaging (MRI) study revealed an extradural cyst extending from T2 to T4 isointense with the cerebrospinal fluid (CSF) on all sequences and did not enhance on T1-weighted post-contrast MRI. Patient underwent T2-T4 laminectomy, en-bloc resection of the lesion was achieved and the histopathological examination objectified an arachnoid cyst. Conclusion: Spinal extradural arachnoid cyst can cause neurologic deficit and the mainstay of treatment in patients with neurological symptoms is surgical removal of the cyst together with ligation of the communicating pedicle and closure of the dural defect.

Parotid Tumors

F.NA.C has been used for ages as a safe and economical tool for fast preoperative diagnosis of parotid tumors. It has certain pitfall which sometimes leads to misdiagnosis and consequently it may have affect on treatment of the tumors. Keeping in view of the diverse classification of parotid tumors’ information from cytology should be combined with radiology as well as clinical diagnosis. Aim: To discuss some cases where there was discrepancy between cytological diagnosis and histopathological result and also suggest measures to improve the efficacy of F.N.A.C. Material and methods: The study includes 50 cases of parotid tumours who presented to the  department of ENT at Government medical college Haldwani which is a tertiary referral centre during 2009 to 2016. Only adult patients were included and inflammatory swelling were excluded from the study. All patients evaluated  Contrast enhanced computerized tomography(CECT) and  Magnetic resonance imaging (MRI) followed by Fine needle aspiration cytology .Preoperative diagnosis was made upon the findings of the above investigations and different types of  parotid surgeries  were done. . Final diagnosis was made on  histopathological  examination. Result :The most common tumour  came out to be pleomorphic adenoma (23 cases-46%) followed by mucoepidermoid carcinoma(12cases-24%). In ten  cases there was no clear cut  association between cytological diagnosis and final histopathological diagnosis. Conclusion: FNAC is highly sensitive and specific technique for diagnosis of many salivary gland swellings. FNAC can be used preoperatively to avoid unnecessary surgery and biopsy. Details of clinical information and radiologic features may help the pathologist to arrive at the appropriate diagnosis and reduce false interpretation. Pitfalls may also occur with improper technique of FNAC which can be overcome by proper caution.

We report the case of a 10-year-old girl with a painless slowly growing mass that had developed over the course of 2 years in the left submandibular area. Physical examination revealed a firm painless submandibular mass with no other associated signs. Ultrasound graphics were in favor of a sebaceous cyst. Fine-needle aspiration and magnetic resonance images (MRI) concluded to a pleomorphic adenoma of the submandibular gland. The patient underwent left submandibulectomy. Histopathological examination confirmed the diagnosis of pleomorphic adenoma arising from the submandibular gland. The postoperative course was uneventful. Pleomorphic adenoma of the submandibular gland represents a diagnostic and therapeutic dilemma in children. Preoperative evaluation, including MRI and fine-needle aspiration, is recommended. Total submandibulectomy is also recommended to minimize recurrences and to avoid malignant transformation.

✓ The authors report the case of a 53-year-old woman with monostotic fibrous dysplasia of the thoracic spine. The patient presented with a 1-month history of pain in the thoracic spinal region. En bloc resection of the lesion was successfully performed via a transthoracic approach, and a histopathological examination confirmed the diagnosis of fibrous dysplasia. At 24-month follow-up examination, pain and vertebral instability were absent. The findings in this case illustrate that, although very rare, monostotic fibrous dysplasia of the thoracic spine should be considered in the differential diagnosis of spinal tumors. Although a consensus for management of this disease has not been achieved, the authors recommend radical removal of all involved bone as well as internal fixation or bone graft—assisted fusion to achieve long-term stabilization.

Needle Aspiration Cytology

Cysticercosis is a systemic parasitic disease caused by the larval form of cestodeT. solium. It has a worldwide distribution and is potentially harmful with variable clinical manifestations. The patient most commonly presents with subcutaneous and muscle involvement in the form of nodular lesions. The other most commonly involved sites include eye, brain, bladder wall, and heart. Cysticercosis can be diagnosed on serology, and radiologically but confirmatory diagnosis is based on histopathological examination of the involved tissue biopsy specimen. Fine needle aspiration cytology is a useful low-cost outpatient procedure tool for preoperative diagnosis of cysticercosis and is absolutely essential for diagnosis of the parasitic lesions in a peripheral hospital, one like ours.

BACKGROUND Papillary thyroid carcinoma is the most common malignancy of the thyroid gland. Fine Needle Aspiration Cytology (FNAC) is a rapid, safe and economic procedure, and has a sensitivity approaching of 93.5 % and specificity close to 90 % for diagnosing papillary thyroid carcinomas. This study aims at correlating the cytological and histological diagnosis to arrive at the rate of concordance and discordance, identify variants of papillary thyroid carcinoma (PTC) on cytology and discuss the cytological mimics of PTC. METHODS Data from cases was collected over a period of three years (2015 - 2018). A descriptive study was done. Cases from Osmania General Hospital representing histologically proven cases of papillary carcinoma thyroid along with their corresponding cytological findings were analysed. Cytosmears were obtained from fine needle aspiration of thyroid lesions using a 26-gauge needle, stained with haematoxylin and eosin (H&E). Thyroidectomy specimens were fixed in 10 % buffered formalin, grossed and paraffin embedded. After processing, sections obtained by microtomy were stained with H & E for histopathologic evaluation. RESULTS The institute received a total of 258 thyroid specimens for histopathology and 686 cases for thyroid FNAC over a period of three years. This study includes 70 cases which had both cytology and histopathology correlation at our institution. 65 cases were diagnosed as PTC on histopathology and correct diagnosis was made on cytology with 73.8 % concordance (48 / 65 cases) and discordance was seen in 26.1 % (17 / 65 cases). 5 cases were misdiagnosed on cytology as PTC, and on histopathological examination were diagnosed as non-PTC. CONCLUSIONS Fine needle aspiration shows variable accuracy for PTC, ranging from 65 % to 90 %. The architectural arrangement of cells in papillary fragments and presence of nuclear features in majority of cells is diagnostic of the conventional variant of PTC. The other variants however, pose a diagnostic dilemma on account of their architectural variation, altered cytomorphology and the scant presence of nuclear features. An increase in the awareness of cytomorphology of variants and also of the mimics of PTC helps improve the diagnostic accuracy on FNAC.
