RESUMO
Pernicious anemia, stemming from Vitamin B12 deficiency and autoimmune processes affecting intrinsic factor production, presents challenges in early diagnosis due to vague initial symptoms. This case report introduces a unique occurrence of pernicious anemia-induced peripheral neuropathy in a patient with concurrent HLA-B27 arthropathy, highlighting the complex interplay of autoimmune mechanisms. While HLA-B27 is not typically associated with pernicious anemia, the case underscores the importance of exploring specific HLA haplotypes in understanding the nuanced manifestation of autoimmune disorders. Comprehensive screening for anti-intrinsic factor and anti-parietal cell antibodies is crucial in individuals with signs of pernicious anemia, especially those with a history of HLA-B27 arthropathy, guiding tailored management strategies. This report contributes to the ongoing exploration of the intricate autoimmune landscape in pernicious anemia.
RESUMO
A case is presented in which COVID-19 pneumonia led a young male patient to develop a pneumothorax requiring lobectomy and pleurodesis after the resolution of COVID-19 pneumonia. The literature review showed a few similar cases with clear evidence suggesting that prior COVID-19 infection may be considered a risk factor for pneumothorax. It is crucial for clinicians to take such risk factors into consideration for better clinical outcomes.
RESUMO
Sarcoidosis is a multisystem inflammatory disease characterized by the presence of noncaseating granulomas. Sarcoidosis can affect any organ of the body, the lung being the most affected. Sarcoidosis rarely affects the thyroid gland, and only a few cases of thyroid-related sarcoidosis have been reported in the literature. Herein, we report a case of systemic sarcoidosis with multiple organ involvement in a patient with a solitary left thyroid nodule and benign Fine Needle Aspiration (FNA) findings. The patient was eventually diagnosed with thyroid sarcoidosis using a core needle biopsy of the thyroid nodule. With this case report, we highlight the limitations of the FNA. This case report has the objective to encourage clinicians to include thyroid sarcoidosis in the differential diagnosis of thyroid nodules in patients with systemic sarcoidosis even with unremarkable FNA findings.
