Management of Skin Sarcomas.

Surg Oncol Clin N Am 2022 Jul 31;31(3):511-525. Epub 2022 May 31.

Sarcoma Service - Department of Surgery, Fondazione IRCCS Istituto Nazionale dei Tumori, Via Venezian, 1, Milan 20133, Italy. Electronic address:

Skin sarcomas are tumors that are superficial and small in size in comparison with other sarcomas arising in intramuscular or intrabdominal sites. Skin sarcomas are often underrecognized and misdiagnosed. A high level of suspicion is needed, as early recognition and appropriate management including initial surgery is important for oncologic outcomes. Read More

Dermatofibrosarcoma protuberans with unusual presentation in vulva.

Medicina (B Aires) 2022 ;82(3):441-444

División Ciencias de la Salud, Universidad del Norte, Barranquilla, Colombia.

Gynecological sarcomas are rare and their location in the vulva and vagina has an incidence of 5% of all malignant neoplasms in the female genital tract. We present the case of a 54-year-old patient with a diagnosis of dermatofibrosarcoma protuberans in the vulva, an infrequent pathology with less than 60 cases reported worldwide in this anatomical location. Clinically, it is locally aggressive, due to the proliferation of spindle cells with pleomorphism and frequent mitotic figures infiltrating the reticular dermis and subcutaneous cellular tissue, giving rise to variable size tumors with high local recurrence rates.

Dermatofibrosarcoma protuberans misdiagnosed as sebaceous adenoma and incompletely resected in a child: A case report.

J Clin Lab Anal 2022 May 27:e24500. Epub 2022 May 27.

Department of Radiology, The Second Clinical Medicine Faculty, Inner Mongolia University for Nationalities, Yakeshi, China.

Background: Dermatofibrosarcoma protuberans is extremely rare in children, making a correct diagnosis by clinicians is usually difficult due to its nonspecific manifestations, the recurrence of dermatofibrosarcoma protuberans after resection has always been a perplexing problem for clinicians. Ultrasound plays an irreplaceable role in the assessment of dermatofibrosarcoma protuberans, although there is a limitation in the diagnosis of the tumor.

Case Report: A 10-year-old boy led by his parents sought for surgical treatment because of the growing mass. Read More

Ann Diagn Pathol 2022 Aug 6;59:151967. Epub 2022 May 6.

Department of Laboratory Medicine and Pathology, Mayo Clinic, Rochester, MN 59005, United States of America. Electronic address:

Introduction: Loss-of-function mutations in EED and SUZ12, core components of the polycomb repressive complex 2 (PRC2), occur in >90% of sporadic and radiation-associated malignant peripheral nerve sheath tumors (MPNST) and in roughly 70% of NF1-related tumors. PRC2 inactivation results in loss of H3K27me3 expression and aberrant downstream transcription. H3K27me3 expression is lost in 40-90% of spindle cell MPNST but is not specific. Read More

ETS-related Gene (ERG) is Differentially Expressed in Dermatofibroma (Fibrous Histiocytoma) as Compared With Dermatofibrosarcoma Protuberans and Hypertrophic Scars: A Pilot Immunohistochemical Study.

Appl Immunohistochem Mol Morphol 2022 May 3. Epub 2022 May 3.

Departments of Dermatology.

Immunohistochemical staining can be of great utility in differentiating various cutaneous spindle cell neoplasms, particularly when the histomorphologic appearance of the lesions is inconclusive. Nuclear staining for ETS-related gene (ERG), a highly sensitive endothelial cell marker, has seldom been studied in the context of cutaneous spindle cell neoplasms. Little is known about its specificity for vascular differentiation. Read More

Department of Plastic Surgery and Breast Surgery, Zealand University Hospital (SUH) Roskilde, University of Copenhagen, 4000 Roskilde, Denmark.

Primary dermal sarcomas (PDS) belong to a highly clinically, genetically and pathologically heterogeneous group of rare malignant mesenchymal tumours primarily involving the dermis or the subcutaneous tissue. The tumours are classified according to the mesenchymal tissue from which they originate: dermal connective tissue, smooth muscle or vessels. Clinically, PDS may mimic benign soft tissue lesions such as dermatofibromas, hypertrophic scarring, etc. Read More

Molecular profiling of gene fusions in soft tissue sarcomas by Ion AmpliSeq: a study of 35 cases.

Transl Cancer Res 2022 Mar;11(3):488-499

Department of Pathology, Second Hospital of Shanxi Medical University, Taiyuan, China.

Background: The accurate diagnosis of sarcoma can be difficult as there are over 70 different subtypes. While molecular profiling in soft tissue sarcoma (STS) has gradually been incorporated into routine diagnostics, conventional methods such as fluorescence in situ hybridization (FISH), reverse transcriptase-PCR (RT-PCR), and Sanger sequencing have several drawbacks. By allowing simultaneous analysis of multiple targets and increasing sequencing depth to achieve ultra-sensitivity, next-generation sequencing (NGS) can not only detect common genetic abnormalities without prior assumptions but also identify uncommon or even new variants.

Department of Plastic and Reconstructive Surgery, Southmead Hospital, Southmead Road, Bristol, BS10 5NB, UK.

Opinion Statement: Paediatric dermatofibrosarcoma protuberans (DFSP) is a rare soft tissue malignant tumour which displays aggressive local behaviour and has low metastatic potential. The diagnosis is often delayed as DFSP is usually mistaken for other skin conditions, particularly in the early stages of disease. DFSP tends to follow an indolent course after the initial presentation with what is often described as a "rubbery lump". Read More
