[Acral papular lichen myxedematosus].
ABSTRACT In 1986 Rongioletti introduced the term acral persistent papular mucinosis for persistent papules on the dorsum of the hands and distal forearms. Skin specimens reveal mucin deposits which resemble those in lichen myxedematosus (LM). Laboratory results are usually unremarkable. Our 54-year-old female patient showed a 2 1/2 year history of skin lesions in the typical acral distribution pattern. This entity appears to be an acral papular subtype of LM. In the classification of LM, acral papular lichen myxedematosus should replace the discrete papular form. This latter form has been well known for many years, but is not sufficiently definable and is of secondary clinical importance.

ABSTRACT: Angiosarcoma that develops on a limb with chronic lymphedema is called Stewart-Treves syndrome. This typically appears as a complication of a long course lymphedema located on the arm, after mastectomy and/or radiotherapy due to breast cancer.There are cases of Stewart-Treves syndrome in chronic lymphedema in the upper limb contralateral to the breast treated for cancer and in chronic lymphedema of the leg.We present two cases of this syndrome. The first corresponds to a typical syndrome of Stewart-Treves in an 83-yearold woman who was diagnosed of angiosarcoma in a chronic lymphedema territory secondary to mastectomy and radiotherapy due to breast cancer. The second case is much rarer, since it is a case of diffuse angiosarcoma of the leg in a 42-year-old man with a history of lymphedema.Due to the aggressive nature of this syndrome, knowledge and research on its treatment are necessary.Actas Dermo-Sifiliográficas 10/2006; 97(8).

ABSTRACT: Acral persistent papular mucinosis is a rare subtype of localized lichen myxedematosus. For half a century, this disease has endured a controversial and constantly evolving classification. We describe a patient who presented with discrete, flesh-colored papules on the hands, wrists, and forearms in a distribution consistent with acral persistent papular mucinosis. Histology was also constant with this disease, showing a well-circumscribed deposition of mucin in the upper and mid dermis that spared a small grenz zone. The changing nomenclature and diagnostic requirements of acral persistent papular mucinosis that have allowed it to remain a topic of debate are examined through a comprehensive review of the literature. All reported cases are reviewed.Journal of the American Academy of Dermatology 01/2005; 51(6):982-8. DOI:10.1016/j.jaad.2004.07.002 · 5.00 Impact Factor
