Medical Terminology Guide

Overview Definition Pronunciation Clinical Significance Review

acantholysis

/əˌkænˈθɒlɪsɪs/
Noun Medical term

Definition:Loss of intercellular connections between keratinocytes in the epidermis

Etymology:From Greek "akantha" (thorn) + "lysis" (loosening)

📚 Core Concepts

Pathological Process

Disruption of desmosomal attachments between epidermal cells

Acantholysis results in intraepidermal blister formation.
Acantholysis leads to separation of keratinocytes.
Pathology

Associated Conditions

Characteristic feature of pemphigus vulgaris

Acantholysis is diagnostic for pemphigus disorders.
Acantholysis may occur in Darier's disease.
Dermatology

Histological Finding

Microscopic appearance of rounded keratinocytes

Acantholysis creates "tombstone" basal cells.
Acantholysis shows free-floating keratinocytes.
Histopathology

"Acantholysis" is a specialized histopathological term primarily used in dermatopathology and blistering disorder diagnosis.

🔄 Usage Comparison

Medical Context

The biopsy demonstrated acantholysis with suprabasal clefting.

Autoantibodies cause acantholysis in pemphigus.

This case shows extensive acantholysis throughout the epidermis.

Clinical Significance

Acantholysis confirms pemphigus vulgaris diagnosis.

Presence of acantholysis requires immunobullous workup.

Severe acantholysis correlates with disease activity.

Clinical Correlation

Identify correct statements:

1. Acantholysis only occurs in autoimmune disorders.
2. Acantholytic cells are pathognomonic for melanoma.
3. The degree of acantholysis correlates with disease severity in pemphigus.

1. Incorrect - Also occurs in genetic disorders like Darier's disease

2. Incorrect - Characteristic of pemphigus, not melanoma

3. Correct - More extensive acantholysis indicates active disease
