Coronavirus as a trigger of lymphocytic hypophysitis in an adolescent girl: An exceptional case report.

INTRODUCTION AND IMPORTANCE: Lymphocytic hypophysitis is an underestimated disease and the pathogenesis is still poorly elucidated. Post-coronavirus lymphocytic hypophysitis is a new emerging entity. CASE PRESENTATION: A 16-year-old previously healthy girl presented with pituitary tumor syndrome. She suffered from frontal headaches, polyuria-polydipsic syndrome, and impaired visual acuity. She was diagnosed with COVID-19 infection three weeks before. Contrast-enhanced magnetic resonance imaging (MRI) revealed pituitary enlargement with intense homogenous enhancement postgadolinium on T1 weighted images. The diagnosis of lymphocytic hypophysitis was made after ruling out other differential diagnosis. She was started on methylprednisolone. Improvement of clinical symptoms was seen on day 5 with a significant decrease in headache intensity. CLINICAL DISCUSSION: The article summarizes data from cases reported in the literature and our case to highlight coronavirus as a new trigger of lymphocytic hypophysitis. Despite the rarity of this complication, patients with a suspicion of hypophysitis after a recent COVID-19 infection should be carefully evaluated. CONCLUSION: COVID-19 infection can cause lymphocytic hypophysitis. However, it seems premature to conclude on the causal link between COVID-19 and endocrine diseases. Further studies on larger samples are needed to comprehend the pathogenesis of autoimmune endocrinopathies after COVID-19 infection.

Primary adrenal mature teratoma: A rare case report and review of literature.

Introduction: Teratoma is a germ cell tumor, deriving from totipotent cells. Teratomas usually occur in gonads and are rarely extra-gonadal. The adrenal location is exceptional. Only few cases of primary adrenal teratomas have been reported in literature, mainly in young patients. Case report: We report the case of a 56-year-old female patient who presented with pyrosis, dyspepsia and abdominal pain that was evolving for 5 months. The abdominal computed tomography revealed a voluminous mass of the right adrenal gland and the hormonal evaluation was normal. The patient underwent an open transperitoneal adrenalectomy and the histopathological examination of the specimen confirmed the diagnosis of mature teratoma. Discussion: Adrenal teratomas are commonly asymptomatic and their diagnosis depends mostly on radiologic findings. Malignant transformation is very rare. Surgical excision is the mainstay of treatment with a good prognosis. Conclusion: Open surgery should always be considered in large and adhering teratoma tumors of the adrenal gland. Some pathologic features and tumorigenesis of adrenal teratomas are not entirely elucidated, thus the importance of larger studies in order to comprehend this pathological entity.
