Lateral aberrant ectopic thyroid is very rare, comprising only 1%–3% of all the ectopic thyroid tissue. Clinically, these lesions are mistaken for lymph node swelling or metastatic tumour. Primary carcinoma in lateral aberrant ectopic thyroid with normal active native thyroid is very uncommon. We report a case of papillary carcinoma in lateral aberrant ectopic thyroid tissue, with a completely normal native thyroid gland in a 53-year-old man, who presented with a massive swelling in the lateral aspect of the neck clinically and radiologically diagnosed as a malignant soft tissue tumour with differential diagnosis of malignant lymphoma. Fine needle aspiration cytology revealed metastatic papillary carcinoma. In toto excision of the soft tissue mass along with subtotal thyroidectomy was performed. Histology of the mass revealed papillary carcinoma of lateral aberrant ectopic thyroid, while the thyroid gland did not show evidence of malignancy. The postsurgical period was uneventful, and the patient underwent radioiodine ablation.
Endometriosis is a disease seen in 10-15% of reproductive age women, which involves the pelvic cavity. The urinary tract is affected in 1% cases of pelvic endometriosis, while 0.1-0.4% of ureteric endometriosis which is extremely rare. Ureteric endometriosis poses a diagnostic challenge, as it can be asymptomatic or can present as renal colic. It can lead to a severe burden on kidneys like hydroureteronephrosis, renal atrophy, and irreversible renal failure. Authors report an extremely rare case of ureteric endometriosis in a postmenopausal female, who presented with complaints of lower backache. Radiologically diagnosed as neoplastic ureteric stricture.
Pigmented villonodular synovitis (PVNS) is a rare benign neoplasm involving the synovial joints and tendon sheaths. It can be classified into localised and diffuse type. The diffuse type of PVNS is larger and very aggressive, clinically mimicking as soft tissue sarcoma. Radiological investigation can aid in knowing the relation of the mass to the joint cavity and invasion of surrounding structures. A biopsy can pose a diagnostic challenge for pathologists. Surgical excision is the treatment of choice. Histopathological examination is necessary for a definite diagnosis.

Congenital pulmonary airway malformation (CPAM) is a broad spectrum of congenital cystic lung lesions caused by the arrested bronchoalveolar development. Approximately, 80% of CPAMs are diagnosed prenatally or during the neonatal period when patients present with respiratory failure and cyanosis. CPAM is often associated with other organ anomalies and aplasia, and they have poor prognoses. Many CPAMs are detected in infants and school-age children, and infections like pneumonia trigger these diagnoses. It rarely manifests in adults. These often get missed because of the superadded diseases, and hence, it is essential to have a correct approach to their diagnosis to avoid misdiagnosis.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
