Résumé
A 69-year-old woman developed erythema and skin thickening on her breast 1 year after ipsilateral breast cancer therapy, which included lumpectomy, adjuvant chemotherapy (adriamycin, cyclophosphamide, and paclitaxel), and whole breast radiation (42.5 Gy in 16 fractions with boost to 48 Gy). Within a month of presentation, there was erythema across the whole breast, fullness, nipple stretching, skin thickening, and peau d’orange (Fig 1). The deeper tissue was soft and pliable, with no palpable masses. She denied pain, fever, and other constitutional symptoms. A punch biopsy showed dermal thickening and fibrosis and pronounced perivascular inflammation with the infiltration of lymphocytes (Fig 2).Fig 2View Large Image Figure ViewerDownload Hi-res image Download (PPT) Question 1: Which of the following is the most likely diagnosis?A.Acute radiation dermatitisB.Carcinoma en cuirasseC.CellulitisD.Postirradiation fibrosisE.Radiation-induced morphea (RIM) Answers:A.Acute radiation dermatitis – Incorrect. Acute radiation dermatitis may resemble the above lesion, but, unlike RIM, it presents in a more acute time frame and is histologically characterized by edema, vasodilation, thrombi, and erythrocyte extravasation.1Spalek M. Jonska-Gmyrek J. Galecki J. Radiation-induced morphea—a literature review.J Eur Acad Dermatol Venereol. 2015; 29: 197-202https://doi.org/10.1111/jdv.12704Crossref PubMed Scopus (40) Google ScholarB.Carcinoma en cuirasse – Incorrect. Though cutaneous metastases of breast cancer most commonly present as solitary to multiple erythematous infiltrating papules and nodules, carcinoma en cuirasse may resemble the above lesion. Carcinoma en cuirasse may be histologically characterized by the infiltration of atypical cells (arranged in dense linear sheets) within the dermis and lymph vessel obstruction.1Spalek M. Jonska-Gmyrek J. Galecki J. Radiation-induced morphea—a literature review.J Eur Acad Dermatol Venereol. 2015; 29: 197-202https://doi.org/10.1111/jdv.12704Crossref PubMed Scopus (40) Google Scholar,2Reich A. Samotij D.

Cellulitis may resemble the above lesion and may even cause peau d’orange. However, it is typically poorly demarcated and presents with pain (whereas RIM is more often painful in its later stages). Additionally, cellulitis is histologically characterized by the perivascular infiltration of neutrophils, dermal edema, and lymph vessel dilation.1Spalek M. Jonska-Gmyrek J. Galecki J. Radiation-induced morphea—a literature review.J Eur Acad Dermatol Venereol. 2015; 29: 197-202https://doi.org/10.1111/jdv.12704Crossref PubMed Scopus (40) Google Scholar,3Raff A.B. Kroshinsky D. Cellulitis: a review.JAMA. 2016; 316: 325-337https://doi.org/10.1001/jama.2016.8825Crossref PubMed Scopus (201) Google ScholarD.Postirradiation fibrosis – Incorrect. Postirradiation fibrosis may resemble the above lesion, but, when histologically compared to RIM, it lacks significant inflammatory infiltration and has fibrosis in deeper skin layers (ie, subcutaneous/fascial).1Spalek M. Jonska-Gmyrek J. Galecki J. Radiation-induced morphea—a literature review.J Eur Acad Dermatol Venereol. 2015; 29: 197-202https://doi.org/10.1111/jdv.12704Crossref PubMed Scopus (40) Google ScholarE.RIM – Correct. This clinical picture is most consistent with RIM, which is generally an erythematous, edematous plaque that progresses to induration, violaceous discoloration, peau d’orange, and pain in its later stages. The early stages are histologically characterized by slight dermal collagen thickening and the perivascular/periadnexal infiltration of lymphocytes, and the later stages by prominent dermal fibrosis and a loss of periadnexal adipose tissue and lymphocyte infiltration.1Spalek M. Jonska-Gmyrek J. Galecki J.

Many treatments have shown some efficacy in RIM, including topicals (eg, steroids, calcipotriene, tacrolimus), systemic medications (eg, prednisone, methotrexate), and phototherapy (eg, narrow-band ultraviolet B).1Spalek M.
