Histology And Immunohistochemistry

A five-year-old neutered male Labrador Retriever was presented for recurring severe dyspnoeic episodes. Oral examination performed under sedation revealed a mass originating from the left arytenoid. CT highlighted a large perilaryngeal soft-tissue mass abutting the oesophagus, with a small intralaryngeal component. The mass created a narrowing of the laryngeal lumen and displaced the cranial cervical oesophagus dorsally and to the right. CT also highlighted a second smaller mass rostrally at the level of an oesophageal outpouching, narrowing the caudal aspect of the nasopharynx. The perilaryngeal mass was aspirated under ultrasound guidance. Cytology was suggestive of a tumour arising from skeletal muscle and a rhabdomyosarcoma was suspected. Due to poor prognosis, the patient was euthanased. Postmortem examination confirmed two masses affecting the cranial cervical oesophagus, one of which also invaded the perilaryngeal tissue. Histology and immunohistochemistry provided a final diagnosis of two concurrent oesophageal and perilaryngeal embryonal rhabdomyosarcomas.

A 7-y-old backyard Leghorn chicken ( Gallus domesticus) was submitted to the California Animal Health and Food Safety Laboratory System (CAHFS)–Turlock branch for postmortem examination, with a history of unexpected death. At postmortem examination, a hemorrhagic soft tissue mass was observed in the cervical region. Microscopically, a densely cellular neoplasm of polygonal epithelial cells and small lymphocytes was observed. The microscopic features of the neoplasm in combination with positive immunohistochemistry for pancytokeratin and CD3 were used to classify the lesion as a thymoma. Thymoma was diagnosed in only 5 birds submitted to CAHFS from 1990 to 2019. Thymoma has been described only rarely in birds, and is an unusual diagnosis in backyard chickens.

Soft tissue masses are amongst the commonest complaints encountered in orthopedic practice. Of these, masses found in the hand and the wrist are presented at higher frequency. They are often painful and may cause limitation of movement. This work describes the prevalence and the nature of soft tissue masses in the hand and wrist encountered in routine practice. This work was performed to assess the characteristics of soft tissue mass in the hand and the effectiveness of ultrasonography in the diagnosis of soft tissue masses and their differentiation from other lesions in the hand and wrist. Orthopedic surgical conditions that involve soft tissue in the hand and wrist may remain a diagnostic challenge when clinical diagnosis is uncertain and standard X-rays are non-diagnostic. High resolution ultrasound is widely available, non-invasive, without damage of radiation, imaging modality that can help the diagnosis. We reviewed retrospectively 25 patients with soft tissue masses. We compared the ultrasound findings with the histological findings in seven operated patients. A substantial majority of these lesions occurred in the right hand: 79% of the lesions were in the dorsal aspect of the hand, of which 37% were distal to the wrist joint, among them 42% at wrist either radial or ulnar; and 21% of the lesions were found in the volar aspect, among them 17% at wrist aspect, either radial or ulnar side. No predisposing factors could be found. The findings of this study reaffirm the utility of ultrasonography as primary diagnostic tool in routine orthopedic practice.

SummaryA 10-year-old spayed female Golden Retriever was admitted with chronic lameness of the right hind limb. A tibial plateau leveling osteotomy (TPLO) had been performed on this leg approximately three years previously. A progressively growing soft tissue mass, affecting the right stifle, previously treated with TPLO was biopsied and found to be a histiocytic sarcoma. Previously proposed links between the development of neoplasia in the stifle region and the presence of chronic synovitis, osteotomy, orthopaedic implants, and specifically the Slocum TPLO plate, are briefly discussed.

Haemangioma of the thyroid gland is extremely rare. We report a case of a cavernous haemangioma of the neck that was located both inside and outside the thyroid gland of a 21-year-old man. Ultrasonography of the neck revealed numerous calcified nodules. Computed tomography (CT) showed a large calcified soft tissue mass in the right lobe of the thyroid. Based on the imaging findings a papillary thyroid carcinoma was suspected, but examination of the surgical specimen revealed a huge cavernous haemangioma containing numerous phleboliths.

Lipoblastoma of the hand is a rare benign tumour of infancy. Although benign, the tumour can present as a large mass. We present a case of a two-year-old female with a large, slowly growing soft tissue mass between the second and third metacarpal of the right hand. After excision of the mass, the deep transverse metacarpal ligament (DTML) was reconstructed using a free tendon graft from the extensor indicis propius (EIP).

A 4.5-year-old llama was admitted for evaluation of a firm mass rostral and ventral to the medial canthus of the left eye. Mucopurulent nasal discharge and absence of airflow through the left nostril were noted. Radiographs of the skull revealed a sharply demarcated soft tissue mass with faint mineralization. Endoscopy of the nasal passages revealed a mucosa-covered mass originating in the area of the second premolar, extending to the edge of the soft palate, and obstructing the airway. Examination of the oral cavity revealed a missing second molar and a mass protruding 2-cm from the empty alveolus. An ossifying fibroma, a previously unre-ported tumor in llamas, was diagnosed at postmortem examination.

Smooth muscle tumors (SMTs) typically fall under either benign leiomyoma or malignant leiomyosarcomas based on histologic characteristics. SMTs that cannot be diagnosed as benign or malignant are then labeled as smooth muscle tumors of uncertain malignant potential (STUMP). A 31-year-old male presented with the right abdominal pain for 6 months. Imaging showed an enhancing soft-tissue mass arising from the right renal vein. A pre-operative biopsy confirmed STUMP of renal vein, and the patient underwent surgical resection of the mass with partial nephrectomy. Imaging and pathologic findings play a crucial role in an accurate pre-procedural diagnosis of unusual SMTs.

Choristoma is a term which refers to the presence of histologically normal tissue in a heterotopic location; hepatic choristoma is a condition in which hepatic tissue can be found in abnormal locations above or below the diaphragm, the gallbladder wall being the most frequent heterotopic site for implantation, this disease is usually asymptomatic and is rarely detected preoperatively with imaging studies due to a general lack of knowledge of this entity. We present the case of a 37 year old male patient who presented with acute abdominal pain in the right upper quadrant, colicky in nature, accompanied by nausea and vomiting; a HIDA 99 mTc scan revealed gallbladder diskynesia as well as a radiolucent bilobulated image. Upon laparoscopy, we encountered two masses on the superoanterior gallbladder wall and Hartmann´s pouch, which upon histopathological specimen examination revealed the presence of hepatic choristoma. This entity should be considered whenever a soft tissue mass is reported on the anterior gallbladder wall on imaging studies; It has been reported that hepatic choristoma is at higher risk for development of hepatocellular carcinoma and should be removed en bloc with the gallbladder.

Tuberculous lymphadenitis is an uncommon form of extrapulmonary tuberculosis We report on a case of isolated Cervicomediastinal tuberculous lymphadenitis without parenhimal involvement. A 49-year old woman was hospitalized with a four week history of night sweats and weight loss. Plain chest radiography disclosed mediastinal mass of the right side. Echocardiographic examination revealed a soft tissue mass below the ascending aorta and aortic arch causing moderate narrowing of the right ventricular outflow tract and the main pulmonary artery. Computed tomographic scanning showed soft tissue mass in the middle mediastinum surrouding the great vessels extending posteriorly with moderate compression of trachea. Histological examination of the cervical mass revealed caseating granuloma containing acidalcohol fast bacillus. Antituberculous chemiotherapy was started.
