An eight-year-old, neutered male, domestic shorthair cat was referred with a four-day history of acute vomiting. Hypercalcemia was identified on serum biochemical testing. Thoracic radiographs showed multiple pulmonary nodular densities. Postmortem and histopathological examination identified the nodules as bronchogenic adenocarcinoma with metastases to the tracheobronchial lymph nodes, diaphragm, and parietal pleura. To the authors' knowledge, this is the first reported case of hypercalcemia of malignancy associated with bronchogenic adenocarcinoma in a cat.

A 16-year-old, neutered male, domestic shorthaired cat was presented with a history of progressive lethargy and decreased appetite. Serum biochemical profile demonstrated hypercalcemia, and thoracic radiographs and computed tomography were consistent with pulmonary neoplasia. A thoracotomy was performed, and a pulmonary mass was removed. Histopathology diagnosed a bronchogenic adenocarcinoma, and calcium levels returned to normal limits after excision of the mass. While bronchogenic adenocarcinoma has been a suspected cause for hypercalcemia in cats, to the authors’ knowledge, this is the first proven account.

Purpose: To describe a rare presentation of a case of intraocular non-teratoid medulloepithelioma with teratoid metastases in ipsilateral intraparotid lymph nodes. Case description: A 9-year-old male child with previous history of ciliary body non-teratoid medulloepithelioma presented with a swelling in the right pre-auricular region for 1 month. Magnetic resonance imaging and positron emission tomography–computed tomography showed a right intraparotid mass with enlarged ipsilateral cervical lymph nodes. A core biopsy was taken from the lesion, which on microscopy showed a tumor composed of small round cells arranged in cords, tubules lined by multilayered cells, and in cribriform pattern. These cells were embedded in a hypocellular, loose myxoid matrix. Based on the histopathological characteristics and previous history, a diagnosis of medulloepithelioma metastastic to ipsilateral parotid gland was made. The patient underwent right total conservative parotidectomy and bilateral neck dissection. Histopathological examination revealed metastatic medulloepithelioma in five out of eight intraparotid lymph nodes, with extranodal extension into the adjacent parotid parenchyma. Foci of hyaline cartilage were identified within the tumor, leading to a diagnosis of metastatic teratoid medulloepithelioma. Conclusion: Intraparotid lymph node metastases from intraocular medulloepithelioma is a rare possibility and we recommend that the parotid should be evaluated in cases of intraocular medulloepithelioma at initial presentation as well as during the follow-up period. Also, metastasis should be considered in all pediatric patients with solitary mass lesions showing unconventional histology for a primary parotid neoplasm.

A 6 yr old castrated male English springer spaniel was evaluated with a 1 mo history of progressive right forelimb lameness with recent swelling around the elbow joint. Physical examination findings included lameness of the right forelimb, muscle atrophy around the right shoulder, grade 2/6 heart murmur, and moderate dental disease. Results of a complete blood cell count and serum biochemical analysis were unremarkable with the exception of a mildly increased alkaline phosphatase (368 U/L; reference range, 128–328 U/L). Radiographs of the right elbow revealed a mixed lytic and proliferative osseous lesion most consistent with either neoplasia or infection. Thoracic radiographs and the echocardiogram were unremarkable. Fine-needle aspiration of the bone lesion was performed. The cytological diagnosis was chondrosarcoma. The right forelimb was amputated and the axillary lymph nodes were collected. Histopathological examination of the bone lesion and axillary lymph nodes revealed chondrosarcoma with metastasis to the lymph nodes. Lymph node metastasis of chondrosarcoma is rare and needs to be further evaluated as a prognostic indicator.

Canine transmissible venereal tumor (TVT) is a round cell neoplasm occurring on the external genital mucosa of male and female dogs. Transmission is by cell implantation during coitus, licking, or other interaction between an affected dog and a susceptible host. Metastasis of the tumor rarely occurs. This report describes an unusual presentation of TVT with intraocular involvement and inguinal lymph nodes metastasis. The subject was a six-year-old, intact, male, Brazilian Terrier dog with a history of abnormal masses in the right eye, penis and several subcutaneous nodules in the inguinal area. Histopathological examination of the eye specimens as well as cytologic examination of penile mass and subcutaneous nodules revealed similar findings. The examination revealed round cells containing a large nuclei with prominent, central located nucleoli and a pale cytoplasm containing few small, clear round vacuoles. Histologically, the subcutaneous nodules in the inguinal area were lymph nodes. The diagnosis of TVT with intraocular involvement and lymph nodes metastasis was based on clinical, cytologic and histopathologic findings.

A 20-y-old female llama ( Lama glama) was euthanized after a history of chronic dyspnea and osteoarthritis. At autopsy, the lungs were covered by clear gelatinous material and expanded by firm, variably discrete, tan-white nodules up to 8 cm diameter containing tan-white, viscous material. The tracheobronchial lymph nodes were firm and enlarged up to 6 × 4 × 3 cm; the thoracic aorta and carotid arteries were lined by hard, tan-white, mineralized intimal plaques. Histologic examination of lung revealed numerous 10–20 μm diameter yeasts with clear 1–2 μm thick double-contoured walls, central basophilic nuclei, and frequent broad-based budding, consistent with Blastomyces dermatitidis. DNA sequencing confirmed the diagnosis. B. dermatitidis should be considered in the differential diagnosis of pulmonary disease in llamas.

Popliteal artery thrombosis may present as a complication of an osteochondroma located in the vicinity of the knee joint. This is a case report of a 26-year-old man with symptoms of the right lower extremity ischaemia without a previous history of vascular disease or trauma. Plain radiography, magnetic resonance angiography and Doppler ultrasonography documented the presence of an osteochondrous structure of the proximal tibial metaphysis, which displaced and compressed the popliteal artery, causing its occlusion due to intraluminal thrombosis..The patient was operated and histopathological examination confirmed the diagnosis of osteochondroma.

Introduction: Spinal tuberculosis is the most common manifestation of extrapulmonar y tuberculosis. A combination of leprosy and tuberculosis is a rare entity.Case report: A 44-year-old male patient working as a laborer presented to our hospital with complaints of severe back pain and swelling over the back, difficulty in walking, associated with constitutional symptoms. On admission, he was febrile and had leukocytosis. Initial spine X-ray showed end plate destruction and increase in soft tissue shadow at the level of T8-T9. CT spine revealed thoracic paravertebral collection extending from T7 to T9 levels, suggest ive of tuberculous spondylitis with cold abscess. Patient refused a transpedicular biopsy and was started on anti-tubercular therapy. Two weeks after commencement of treatment, he developed worsening back pain and weakness of the lower extremities. MRI spine showed a paravertebral abscess and posterior soft tissue edema involving level of T7 to T11. Patient underwent a posterior decompression, debridement and posterior instrumentation. He was discharged well, there was improvement of his lower limb power. Upon clinic review, he complained of multiple hyperpigmented, painless, nonpruritic skin lesions over the trunk and back. No previous history of eczema, psoriasis and Tinea corporis. Given the history of allergy, initial impression was hypersensitivity reaction towards the titanium implants, and he was started on anti-histamines. However, there was no improvements seen. Histopathological examination of skin lesions revealed presence of granuloma within the dermis layer, composed of epitheloid, histiocytes, lymphocytes and plasma cells. Wade-Fite stain for Mycobacterium leprae is positive. Slit skin smear shows multibacillary leprosy. Patient was started on multidrug therapy (rifampicin, clofazimine and dapsone) for 1 year. He has recovered well.International Journal of Human and Health Sciences Supplementary Issue: 2019 Page: 33

AbstractScopolamine is an alkaloid which acts as competitive antagonists to acetylcholine at central and peripheral muscarinic receptors. We report the case of a 41-year-old male convict with a 27-year history of cannabis abuse who suddenly died in the bed of his cell after having smoked buscopan® tablets. Since both abuse of substances and recent physical assaults had been reported, we opted for a comprehensive approach (post-mortem computed tomography CT (PMCT), full forensic autopsy, and toxicology testing) to determine which was the cause of the death. Virtopsy found significant cerebral edema and lungs edema that were confirmed at the autopsy and at the histopathological examination. Scopolamine was detected in peripheral blood at the toxic concentration of 14 ng/mL in blood and at 263 ng/mL in urine, and scopolamine butyl bromide at 17 ng/mL in blood and 90 ng/mL in urine. Quetiapine, mirtazapine, lorazepam, diazepam, and metabolites and valproate were also detected (at therapeutic concentrations). Inmates, especially when they have a history of drug abuse, are at risk to use any substance they can find for recreational purposes. In prisons, active surveillance on the management and assumption of prescribed drugs could avoid fatal acute intoxication.

Differential diagnosis of globus sensation in an otherwise asymptomatic patient should include hypopharyngeal fibrovascular polyp to avoid potentially fatal complications like airway compromise following regurgitation. We present a case of a 74-year-old man with a 13-cm long hypopharyngeal fibrovascular polyp with 9 months history of globus sensation. A narrow stalk of the giant polyp allowed endoscopic removal and complete resection with the CO2 laser. Histopathological examination was conclusive for the fibrovascular polyp.
