The congenital absence of major salivary glands is an infrequent disorder, in which several glands are usually involved at the same time. Aplasia of unilateral submandibular (SM) gland is a very rare finding. Clinical presentation is variable. While some patients have no symptoms, others report difficulty in chewing and swallowing due to dry mouth, and even dental caries. Diagnosis of salivary gland aplasia can be made with a variety of imaging techniques, which include sonography, CT or MRI, sialography or isotope scans (technetium T99m-pertechnetate). We report the case of a 30-year-old man presenting with a gradually progressive neck mass, because of unilateral SM gland hypertrophy associated with contralateral SM gland aplasia.

BACKGROUND The thyroglossal duct cyst, which develops from the midline migratory tract between the foramen cecum and the anatomic location of the thyroid, is the most prevalent congenital abnormality of the neck, accounting for about 70% of all cervical neck masses in children and 7% in adults. Only up to 1% of these abnormalities contain malignant thyroid tissue, with 90% of those cases being papillary thyroid carcinoma. Thyroglossal duct cyst is rarely linked to carcinoma.

This case report provides details of the first documented case of pituitary stalk interruption syndrome (PSIS) with coexistent focal cortical dysplasia (FCD) in a young boy. The child's initial presentation was an afebrile, generalised tonic-clonic seizure associated with postictal drowsiness. During his first episode, the physical examination revealed a short, obese child with a micropenis and left cryptorchidism.

Objectives: To evaluate the performance of a 3D V-Net-based segmentation model of adrenal lesions in characterizing adrenal glands as normal or abnormal.
Methods: A total of 1086 CT image series with focal adrenal lesions were retrospectively collected, annotated, and used for the training of the adrenal lesion segmentation model. The dice similarity coefficient (DSC) of the test set was used to evaluate the segmentation performance.

Extensive research on COVID-19 has revealed a notable link between the disease and thyroid disorders, highlighting complex interactions between thyroid hormones, immunomodulatory signaling molecules within the thyroid gland, and viral infections. This study evaluated the relationship between thyroid function and COVID-19 in Iraqi patients at Adiwaniyah Teaching Hospital. The cohort for this investigation comprised all patients who were admitted to the isolation center at the Teaching Hospital during the timeframe extending from January 2024 to June 2024.

Kenny-Caffey syndrome 2 (KCS2) is a rare cause of hypoparathyroidism, inherited in an autosomal dominant mode, resulting from pathogenic variants of the gene, which is implicated in intracellular pathways regulating parathormone (PTH) synthesis and skeletal and parathyroid gland development. : The case of a boy is reported, presenting with the characteristic and newly identified clinical, biochemical, radiological, and genetic abnormalities of KCS2. : The proband had noticeable dysmorphic features, and the closure of the anterior fontanel was delayed until the age of 4 years.
