Dermatofibrosarcoma Protuberans: The role of tissue expansion in reconstructive surgery of the scalp

International Journal of Surgery Case Reports
Richard MaguireAlfred Lam

Abstract

Dermatofibrosarcoma Protuberans is an uncommon tumour, making up less than 0.1% of all malignancies. With regards to soft tissue tumours; this pathology is thought to make up less than 2% of the sum total. Traditionally treatment has been wide local excision, with or without adjuvant radiotherapy. We present a case of a 42 year old man referred by his GP with a lump on the right parietal region of the scalp. An USS done by his GP revealed a complex hypoechoic cystic mass, some 2cm×1cm×2cm. Excision biopsy was performed and on review of the pathology it was noted that the lesion was a Dermatofibrosarcoma Protuberans. Due to the relatively low grade of this sarcoma, it was decided to treat with wide local excision with 2-4cm margins. The expected residual scalp defect would be difficult to close with local flaps. To facilitate closure tissue expansion was undertaken for 6 weeks prior to definitive surgery. With regards to tumours of the head and neck, use of a tissue expander has been recommended to improve cosmetic outcomes following respective surgery with wide margins. Ultimately the timing of tissue expansion i.e. before/after resection of the tumour, must weight the risk of delayed resective surgery on prognosis against the ...Continue Reading

COVID-19

Coronaviruses encompass a large family of viruses that cause the common cold as well as more serious diseases, such as the ongoing outbreak of coronavirus disease 2019 (COVID-19; formally known as 2019-nCoV). Coronaviruses can spread from animals to humans; symptoms include fever, cough, shortness of breath, and breathing difficulties; in more severe cases, infection can lead to death. This feed covers recent research on COVID-19.

Blastomycosis

Blastomycosis fungal infections spread through inhaling Blastomyces dermatitidis spores. Discover the latest research on blastomycosis fungal infections here.

Nuclear Pore Complex in ALS/FTD

Alterations in nucleocytoplasmic transport, controlled by the nuclear pore complex, may be involved in the pathomechanism underlying multiple neurodegenerative diseases including Amyotrophic Lateral Sclerosis and Frontotemporal Dementia. Here is the latest research on the nuclear pore complex in ALS and FTD.

Applications of Molecular Barcoding

The concept of molecular barcoding is that each original DNA or RNA molecule is attached to a unique sequence barcode. Sequence reads having different barcodes represent different original molecules, while sequence reads having the same barcode are results of PCR duplication from one original molecule. Discover the latest research on molecular barcoding here.

Chronic Fatigue Syndrome

Chronic fatigue syndrome is a disease characterized by unexplained disabling fatigue; the pathology of which is incompletely understood. Discover the latest research on chronic fatigue syndrome here.

Evolution of Pluripotency

Pluripotency refers to the ability of a cell to develop into three primary germ cell layers of the embryo. This feed focuses on the mechanisms that underlie the evolution of pluripotency. Here is the latest research.

Position Effect Variegation

Position Effect Variagation occurs when a gene is inactivated due to its positioning near heterochromatic regions within a chromosome. Discover the latest research on Position Effect Variagation here.

STING Receptor Agonists

Stimulator of IFN genes (STING) are a group of transmembrane proteins that are involved in the induction of type I interferon that is important in the innate immune response. The stimulation of STING has been an active area of research in the treatment of cancer and infectious diseases. Here is the latest research on STING receptor agonists.

Microbicide

Microbicides are products that can be applied to vaginal or rectal mucosal surfaces with the goal of preventing, or at least significantly reducing, the transmission of sexually transmitted infections. Here is the latest research on microbicides.
