Summary
Pleomorphic dermal sarcoma (PDS), a rare mesenchymal tumor, can be mistaken for similar conditions. This case report details a large PDS scalp lesion and its successful surgical management.
Area of Science:
- Dermatology
- Oncology
- Pathology
Background:
- Pleomorphic dermal sarcoma (PDS) is a rare, aggressive mesenchymal neoplasm.
- Distinguishing PDS from atypical fibroxanthoma (AFX) is challenging due to overlapping clinical and histological features.
Observation:
- A 77-year-old male presented with a rapidly growing, large nodular scalp lesion.
- The lesion measured 3.3 cm and was confirmed as invasive pleomorphic dermal sarcoma on pathology.
Findings:
- Histological examination revealed features consistent with pleomorphic dermal sarcoma.
- Complete surgical excision with 2 cm margins was achieved, followed by successful graft healing.
Implications:
- This case underscores the importance of accurate diagnosis of PDS.
- Effective management involves complete surgical resection for favorable outcomes.

Rous Sarcoma virus or RSV was discovered by F. Peyton Rous in the year 1911 as a filterable transmissible agent that could cause tumors in chickens. He won a Nobel Prize for this discovery in 1966. His experiments clearly demonstrated that some cancers could be caused by infectious agents and led to the discovery of many more cancer-causing viruses in animals as well as humans.

Plant tissues are collections of similar cells performing related functions. Different plant tissues will have their own specialized roles and can be combined with other tissues to form organs such as flowers, fruit, stem, and leaves. Two major types of plant tissue include meristematic and permanent tissue.

Vascular plants, which account for over 90% of the Earth’s vegetation, all undergo primary growth—which lengthens roots and shoots. Many land plants, notably woody plants, also undergo secondary growth—which thickens roots and shoots.

Plants grow throughout their lives; this is called indeterminate growth, and it distinguishes plants from most animals. Although certain parts of plants stop growing (e.g., leaves and flowers), others grow continuously—like roots and stems.
