AbstractA parotid gland mass with presenting features of malignancy is a diagnostic and therapeutic challenge. The histological nature of the lesion must be clearly determined before proceeding with facial nerve sacrificing surgery. Although rare, tuberculosis of the parotid gland must be included in the differential diagnosis of a parotid gland mass especially when the social characteristics of the patient suggests a mycobacterial infection. Primary tuberculosis of the parotid gland is generally encountered among populations with a high incidence of pulmonary disease. The difficulty in the differential diagnosis of a parotid gland malignancy may be helped by a high degree of clinical suspicion, since laboratory tests generally do not identify the specific causative organism. This article reports the first case of parotid gland tuberculosis with clinical and radiodiagnostical features simulating malignancy in which the diagnosis was confirmed by the polymerase chain reaction (PCR).

Abstract Efforts to recognize SARS–CoV-2 infection have focused on respiratory symptoms such as cough and shortness of breath. Although it is also well known that SARS–CoV-2 infection can cause gastrointestinal symptoms such as abdominal pain, nausea, vomiting and diarrhoea, there are emerging reports of SARS–CoV-2 infection causing surgical pathology. We present the first case report of SARS–CoV-2 infection directly causing acute appendicitis, first suspected due to highly atypical histological features and later confirmed as polymerase chain reaction positive appendicular tissue sample.

Dogs may be infected by Mycobacterium (M.) tuberculosis, M. bovis, and M. avium complex, and the clinical signs associated with each of these infections may be indistinguishable. Rapid speciation of the infecting organism is desirable because of the public health concerns associated with M. bovis and M. tuberculosis infections. A mycobacterial infection was suspected in the dog of this report based on acid-fast staining of organisms in macrophages obtained from liver aspirates and buffy-coat preparations. Polymerase chain reaction (PCR) analysis of a buffy-coat preparation identified M. avium.

AbstractObjectivesCoronavirus disease (COVID-19) rapidly spread worldwide in a few months and was declared as a worldwide pandemic by WHO in March 2020. Transient benign hyperphosphatasemia (THI) is a benign condition associated with marked elevation of alkaline phosphatase (ALP) without any other kidney, bone, and liver pathologies.Case presentationHerein, we report a previously healthy 16-month-old female patient who developed a secondary transient benign hyperphosphatasemia associated with SARS-CoV-2. Patient whole family’s SARS-CoV-2 real-time reverse transcription-polymerase chain reaction (RT-PCR) results were positive. Since THI is a diagnosis of exclusion, other reasons that may cause ALP elevation should be ruled out. ALP activity decreased and turned to normal ranges within the following month. THI has been reported to be in association with various conditions. Its relationship with many viruses has been reported previously.ConclusionsIf ALP elevation is detected in patients with COVID 19 due to the increasing number of infections, THI should be considered if there is no other accompanying pathology.

Tissue Specimens

A two-year-old, spayed female, miniature schnauzer was evaluated for respiratory distress associated with a compressive cervical mass. Generalized mycobacterial infection was diagnosed from aspirates of several enlarged lymph nodes. Tissue specimens further identified Mycobacterium avium--intracellulare using polymerase chain reaction followed by nucleic acid hybridization. Treatment with enrofloxacin, clofazamine, rifampin, and interferon did not result in long-term success.

Ranch Mink

Severe nonsuppurative meningoencephalitis associated with Aleutian mink disease parvovirus (ADV) infection was observed in adult ranch mink. Brain lesions included severe, locally extensive to coalescing lymphoplasmacytic meningoencephalitis with accompanying gliosis, satellitosis, and mild extension of inflammation into the leptomeninges. ADV was identified in mesenteric lymph node, spleen, brain, and liver of affected mink by polymerase chain reaction techniques. Sequences of the ADV isolate (TH5) revealed 2 unique residues in the region of the viral genome that determines pathogenicity. These findings suggest that certain strains of ADV may preferentially cause disease in the nervous system. ADV infection should be considered in the differential diagnosis of neurologic disorders in mink.
