lncRNA - Long Non-coding RNAs

lncRNA - Long Non-coding RNAs

In humans, more than 80% of the genome gets transcribed. However, only around 2% of the genome codes for proteins. The remaining part produces non-coding RNAs which includes ribosomal RNAs, transfer RNAs, telomerase RNAs, and regulatory RNAs, among other types. A large number of regulatory non-coding RNAs have been classified into two groups depending upon their length – small non-coding RNAs, such as microRNA, which are less than 200 nucleotides in length, and long non-coding RNA...

Classification of Epithelial Tissues: Glandular Epithelium

Classification of Epithelial Tissues: Glandular Epithelium

The glandular epithelium is made of one or more epithelial cells modified to synthesize and secrete chemical substances. Glandular epithelia can be classified based on cell number. Unicellular glands have individual secretory cells scattered across the epithelial monolayer. In contrast, multicellular glands consist of a hollow tubular duct attached to the cluster of secretory cells located in the deep pockets.
Multicellular glands are formed during early development when epithelial budding...

Background:

Microglandular adenosis (MGA) and atypical microglandular adenosis (AMGA) are rare breast lesions.
Carcinoma arising in MGA/AMGA is exceptionally uncommon, with most cases being invasive.
Accurate diagnosis relies on imaging modalities like ultrasound and MRI.

Observation:

A palpable breast mass was noted in a very young Vietnamese woman.
Clinical examination and imaging revealed suspicious lesions categorized as BI-RADS 4a.
The patient presented with a 1-month history of the palpable mass.

Findings:

Histopathology confirmed ductal carcinoma in situ (DCIS) arising from MGA/AMGA.
The diagnosed DCIS was localized within the duct without signs of invasion.
This represents a rare instance of non-invasive carcinoma developing in MGA/AMGA.

Implications:

Highlights the importance of vigilant diagnosis of MGA/AMGA, even in young patients.
Emphasizes the potential for DCIS development within these rare breast lesions.
Early detection and management of localized DCIS in MGA/AMGA can prevent invasive breast cancer.
