Summary
A rare atypical intradermal smooth-muscle neoplasm case highlights a spectrum of smooth muscle tumors. This diagnosis avoids mislabeling, reducing patient anxiety and improving prognosis focus on local recurrence.
Area of Science:
- Dermatology
- Surgical Pathology
- Oncology
Background:
- Reporting a rare case of atypical intradermal smooth-muscle neoplasm.
- Highlighting the diagnostic challenge of intradermal smooth muscle proliferations.
Observation:
- A 58-year-old man presented with a two-year history of a painless chest nodule.
- Histopathology revealed intradermal smooth muscle cell proliferation with atypia and mitoses.
Findings:
- Diagnosis of "atypical intradermal smooth-muscle neoplasm" was suggested.
- This entity represents a spectrum from leiomyoma to leiomyosarcoma.
Implications:
- The terminology offers an alternative to misdiagnosis of sarcoma, mitigating psychological impact.
- Prognosis is primarily related to the risk of local recurrence.

Smooth muscle tissue is a type of muscle tissue that can be found lining various vital organs in the human body, including the lungs, blood vessels, digestive tract, and respiratory tract. This type of tissue is responsible for regulating the movements of these organs, playing crucial roles in the functioning of various systems, including the vascular, digestive, respiratory, and urinary systems.

Skin cancer is a type of cancer that occurs when there is an abnormal growth of skin cells, usually triggered by damage to the DNA within the skin cells. It is primarily caused by exposure to ultraviolet (UV) radiation from the sun or artificial sources like tanning beds. Skin cancer is the most common type of cancer worldwide, and its incidence continues to rise.

Dermis
The dermis might be considered the "core" of the integumentary system, as distinct from the epidermis and hypodermis. It contains blood and lymph vessels, nerves, and other structures, such as hair follicles and sweat glands. The dermis is made of two layers of connective tissue that comprise an interconnected mesh of elastin and collagenous fibers, produced by fibroblasts.
Papillary Layer
The papillary layer is made of loose, areolar connective tissue, which means the collagen...
