# Poorly Differentiated Thyroid Carcinoma in a 19-Year-Old Young Female Patient: A Case Report

## TL;DR

This case report describes a rare thyroid cancer in a young woman and highlights its diagnosis and characteristics.

## Contribution

The novelty lies in presenting a rare case of PDTC in a 19-year-old female, emphasizing its clinical and histological features.

## Key findings

- Computed tomography identified a solid cystic lesion in the thyroid gland.
- Histopathological examination confirmed the diagnosis of poorly differentiated thyroid carcinoma.

## Abstract

Poorly differentiated thyroid carcinoma (PDTC) is a rare type of thyroid carcinoma that develops from follicular epithelial cells. In terms of morphology and prognosis, PDTC falls between well-differentiated thyroid carcinoma (WDTC) and anaplastic thyroid carcinoma (ATC). The spectrum of malignant thyroid tumors originating from follicles ranges from the fatal ATC at one end to the indolent WDTC at the other. We present a case of a 19-year-old female patient complaining of swelling on the right side of the neck. Computed tomography revealed a solid cystic lesion within the right lobe of the thyroid gland. The diagnosis of PDTC was made through histopathological examination. In this case, we evaluated the histological characteristics of the right lobe of the thyroid gland and presented a case report of PDTC in a young female.
