[Rapid diagnosis for liquid-based fine needle aspiration of thyroid nodules].

Introduction: The discovery of thyroid nodule can be a source of concern for the patient. Fine-needle aspiration is the gold standard for their evaluation. We establish a new rapid diagnosis procedure for liquid-based fine needle aspiration (LB-FNA) of thyroid nodules.

Cytological features and nuclear scores: Diagnostic tools in preoperative fine needle aspiration of indeterminate thyroid nodules with RAS or BRAF K601E mutations?

Introduction: The cytological diagnosis of follicular-patterned thyroid lesions is challenging, especially since the World Health Organisation classification has recognised non-invasive follicular thyroid neoplasm with papillary-like features. These entities are often classified as indeterminate on cytology. Molecular testing has been proposed to help classify indeterminate nodules.

[DICER1 mutated, solid/trabecular thyroid papillary carcinoma in an 11-year-old child].

We report the case of an 11-year-old patient diagnosed with a solid variant of papillary thyroid carcinoma. Papillary thyroid carcinoma (PTC) is the most common thyroid cancer, representing 80-90% of all newly diagnosed thyroid cancers. Among the many variants described, solid/trabecular variant of papillary thyroid carcinoma is a rare entity and account for 3% of thyroid cancers.

[Multiple lung carcinoma: Primary or intrapulmonary metastasis?].

Multiple lung carcinomas are 5 to 11,5% of lung carcinomas. The distinction between primary lung carcinomas from carcinomas with intrapulmonary metastasis is essential for optimal patient management. The histopathological analysis is very useful but it has to be completed by genotypic assessment using molecular biology (NGS).
