Ovarian Dysgerminoma

Dysgerminoma is a rare malignant neoplasm, associated with hormonal dysfunctions, which occurs in canine and feline females from middle age to elderly, without racial predisposition. In the present report, we described a case of ovarian dysgerminoma in a dog, only abdominal distension, persistent vulvar bloody discharge and apathy. The animal in question underwent exploratory laparotomy, where general neoformations were detected in the ovaries, and a lymph node with abnormal characteristics was also found. Therefore, surgery for ovariosalpingoisterectomy and puncture of a fragment of the lymph node altered for incisional biopsy was performed. The diagnosis was made through histopathological examination of the ovaries of the fragment derived from the lymph node, the result of which indicated the presence of dysgerminoma in both ovaries and in the lymph node, characterizing a metastasis. In view of this result, the chemotherapy protocol with the association of carboplatin and vinblastine was instituted, which proved to be effective and not very toxic to the animal, with no clinical sign of metastasis being identified after its use.

Diffuse Abdominal Pain

A 18 years old boy presented with severe diffuse abdominal pain, constipation, abdominal distention, fever and diagnosed as a case of perforation as free gas noted under both dome of the diaphragm. After resuscitation, exploratory laparotomy was done and diagnosed as a case of multiple spontaneous leaky perforations of jejunum and ileum 25 to 30 cm from duodeno-Jejunal flexure (DJ) up to terminal ileum. Peritoneal toileting and excisional biopsy of the mesenteric lymph node were done. Operative and postoperative period were uneventful. Histopathological examination of the resected lymph node revealed granulomatous inflammation compatible with tuberculosis. Anti-tubercular therapy was started and continued for 6 months. Patient was discharged on the 12th postoperative day in a good condition. At 3 months of follow up the patient was asymptomatic and thriving well. Free perforation is one of the most feared complications of the intestinal tuberculosis. The terminal ileum is the most common site of perforation, while the majority of (90%) perforations are solitary. Bangladesh Journal of Infectious Diseases 2016;3(2):52-54

Severe Pulmonary Edema

Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), the etiological agent of COVID-19, is considered a zoonotic pathogen mainly transmitted human to human. Few reports indicate that pets may be exposed to the virus. The present report describes a cat suffering from severe respiratory distress and thrombocytopenia living with a family with several members affected by COVID-19. Clinical signs of the cat prompted humanitarian euthanasia and a detailed postmortem investigation to assess whether a COVID-19−like disease was causing the condition. Necropsy results showed the animal suffered from feline hypertrophic cardiomyopathy and severe pulmonary edema and thrombosis. SARS-CoV-2 RNA was only detected in nasal swab, nasal turbinates, and mesenteric lymph node, but no evidence of histopathological lesions compatible with a viral infection were detected. The cat seroconverted against SARS-CoV-2, further evidencing a productive infection in this animal. We conclude that the animal had a subclinical SARS-CoV-2 infection concomitant to an unrelated cardiomyopathy that led to euthanasia.

Castleman disease (CD) or angiofollicular lymph node hyperplasia is an uncommon benign lymphoproliferative disorder. Sometimes it is related to the chronic human herpes virus 8 (HHV-8) infection and the human immunodeficiency virus (HIV). Two clinical entities have been described: a unicentric presentation with the disease confined to a single anatomic lymph node and a multicentric presentation characterized by generalized lymphadenopathy and a more aggressive clinical course. Also, three histopathological subtypes have been described: hyalinevascular, plasma cell, and a mixed variant.We report the case of a 22-year-old young man who was diagnosed as unicentric Castleman Disease. We found on routine physical examination a mass localized in the left abdomen without clinically important constitutional symptoms for 3 years. Abdominal ultrasound and computed tomography scans revealed minimally enhancing soft tissue density lesion & it was seen in the left para aortic region measuring about 71mm x 42 mm in size. The patient subse-quently underwent an exploratory laparotomy. After opening of the abdomen, a lump measuring about 8 cm x 5 cm was found in the mesentery. The whole lump was dissected out and the gap in the mesentery was closed. No other lymphadenopathy was found. The specimen was sent for histopathology which revealed Castleman disease, plasma cell type. The patient completely recovered after surgery. Castleman disease is commonly misdiagnosed as malignant lymphoma, lymphadenitis or ectopic thymoma. So far, its diagnosis is mainly achieved via histopathological examination of surgically obtained tissue. Local or unicentric CD has a good prognosis if surgically excised properly.J Dhaka Medical College, Vol. 23, No.2, October, 2014, Page 256-258

Lymphomas usually involve lymph nodes and other lymphoid tissues, but sometimes occur in non-lymphoid organs, called extra-nodal sites. Primary diffuse extra-lymph node large B-cell lymphoma (DLBCL) of the thyroid and parotid gland have been observed rarely. According to the most accredited guidelines, primary extra-nodal DLBCL of the parotid and thyroid glands should be treated with three cycles of R-CHOP followed by radiotherapy of the involved site (ISRT). Surgery alone is not enough to treat DLBCL. We describe two unusual cases of primary extra-nodal DLBCL in elderly patients treated exclusively with surgical resection, given the inability to apply chemotherapy. Both patients achieved clinical recovery, which was maintained after a follow-up of more than 18 months, despite not having performed the indicated chemotherapy protocol. The two cases presented here, and a few others reported in the literature, should be considered exceptions to the rule, and do not allow the conclusion that surgery alone might be sufficient for complete remission.
