Morphea following surgery and radiotherapy: an evolving problem

Morphea After Liposuction Ultrasonography

Liposuction is a common aesthetic procedure; however, to date, liposuction has not been linked to morphea. The aim was to review cases with a history of liposuction that presented active morphea lesions in the same surgery regions and were confirmed by ultrasound and histology. A retrospective descriptive analysis of the clinical, ultrasonographic, and pathology database took place (2014-2020). Eleven patients met the criteria. Ultrasound supported the diagnosis, and the ultrasonographic signs of activity in these cases matched the features described in the literature in 100% of cases. In summary, morphea may appear after liposuction and ultrasound can support its early detection.

Radiation dermatitis, burns, and recall phenomena: Meaningful instances of immunocompromised district

Ionizing and ultraviolet radiations, as well as burns, can selectively damage and immunologically mark the cutaneous area they act on through direct and indirect mechanisms. After the causal event has disappeared, the affected skin district may appear clinically normal, but its immune behavior is often compromised forever. In fact, irradiated or burned skin areas undergo a destabilization of the immune control, which can lead to either a reduction of immunity (as suggested by the facilitated local occurrence of tumors and infections) or an excess of it (as suggested by the possible local onset of disorders with exaggerated immune response). In other words, these areas become typical immunocompromised districts (ICD). Also, in recall phenomena the damaged skin area usually behaves as an ICD with an exaggerated immune response toward a wide range of drugs (especially chemotherapeutic agents) that prove to be harmless on the undamaged skin surface. The occurrence of any skin disorder on an irradiated, photoexposed, or burned skin area can be defined as an isoradiotopic, isophototopic, or isocaumatopic response, respectively; however, the opposite may also occur when elsewhere generalized cutaneous diseases or eruptions selectively spare irradiated, photoexposed, or burned skin sites (isoradiotopic, isophototopic, and isocaumatopic nonresponse, respectively). The pathomechanisms involved in any secondary disorder occurring on irradiated or burned skin areas may be linked to locally decreased or altered lymph flow (with dysfunction of lymph drainage) on the one hand, and to fibrotic throttling or reduction of peptidergic nerve fibers (with dysfunction of neuroimmune signaling) on the other hand, resulting in a significant dysregulation of the local immune response. Future clinical observations and experimental investigations on radiation dermatitis, sunburns, and thermal or chemical skin injuries should shed new light on the mechanisms regulating regional resistance to infectious agents, local oncogenesis, and district propensity to dysimmune reactions.

Radiotherapy of early breast cancer in scleroderma patients: our experience with four cases and a short review of the literature

PURPOSE

Connective vascular diseases (CVD), including scleroderma, are reported to represent for some researchers a relative contraindication and for others absolute contraindication for radiotherapy. The purpose of our study is to add four new cases to the existing body of international literature and to determine whether women with pre-existing scleroderma who have been surgically treated for early breast cancer could undergo postsurgical radiotherapy without serious early and late complications.

PATIENTS AND METHODS

From May 1998 to November 2010, we irradiated for early breast cancer four patients suffering from pre-existing scleroderma; after conservative surgery, we performed whole breast postoperative radiotherapy of 50.4 Gy total dose to the whole breast plus a 9 Gy boost to the tumor bed. We reviewed the records of all four patients and evaluated the early and late reactions using acute radiation morbidity scoring criteria (Radiation Therapy Oncology Group [RTOG], American College of Radiology, Philadelphia, PA) and late radiation morbidity scoring scheme (European Organisation for Research and Treatment of Cancer [EORTC], Brussels, Belgium and RTOG).

RESULTS

After a median follow-up of 105 months (range 12-155 months) the early and late toxicity concerning the skin, the subcutaneous tissues, the lungs, and the heart have been acceptable and are in full accordance with what have been reported in international literature.

CONCLUSION

This study matches global experience, which shows that patients with scleroderma and breast cancer must be discussed by the multidisciplinary tumor board in order for a personalized treatment strategy to be formulated. Radiation therapy can be proposed as a postsurgical therapeutic option in selected cases.

Morphea as a consequence of accelerated partial breast irradiation

Morphea is a localized form of scleroderma usually unaccompanied by the typical systemic stigmata that characterize progressive systemic scleroderma. It rarely manifests at the site of whole breast external-beam radiation therapy. We present an unusual case of radiation-induced morphea (RIM) that occurred after accelerated partial breast irradiation (APBI) using intracavitary Contura brachytherapy. A 65-year-old white woman was treated for stage IIA invasive ductal carcinoma of the left breast with APBI to a dose of 34 Gy in 3.4-Gy fractions twice daily over the course 5 days with intracavitary brachytherapy. At 1.5 years after completion of APBI, the patient developed an area of tenderness, erythema, and induration at the site of irradiation. A skin biopsy was consistent with morphea. To our knowledge, this is the first case of RIM confined to the area of APBI.
