We report a case of an extremely rare histologic combination of pilomatrix or pilomatrical carcinoma with admixed melanocytes within the same tumor mass. Pilomatrix carcinoma is a neoplasm of low-grade malignancy that is characterized by a […]
Hand-foot syndrome with sclerodactyly-like changes in a patient treated with capecitabine.
Capecitabine, a fluoropyrimidine carbamate with antineoplastic activity, is an oral agent that was developed as a prodrug of 5-fluorouracil and is used in the treatment of metastatic colorectal and breast cancers. Multiple cutaneous adverse effects had been described with the use of […]
Panniculitis as the initial manifestation of brucellosis: a case report.

Granular perineurioma: the first report of a rare distinctive subtype of perineurioma.
Perineurioma represents a relatively recently described neoplasm in the spectrum of benign peripheral nerve sheath tumors composed of perineurial cells staining immunohistochemically positive for epithelial membrane antigen. Although intraneural, extraneural and sclerosing perineurioma, rare variants of perineurioma, do occur, and knowledge […]
Erythema nodosum in association with newly diagnosed hairy cell leukemia and group C streptococcus infection.
Erythema nodosum is an inflammatory reaction of the skin characterized by tender erythematous patches or nodules, usually located on the lower extremities. This report illustrates an association of erythema nodosum with a rare malignancy and an uncommon infectious […]
Primitive nonneural granular cell tumor (so-called atypical polypoid granular cell tumor). Report of 2 cases with immunohistochemical and ultrastructural correlation.
Primitive nonneural granular cell tumors (so-called atypical cutaneous granular cell tumors) were first described in 1991, followed by few case reports, and 2 recent larger series. We report here 2 additional cases in […]
Mycosis fungoides after solid-organ transplantation: report of 2 new cases.

However, the resultant modification of the immune system is associated with an increased risk of several cancers. The most common are skin cancers, and […]
\”Macular arteritis\”: a latent form of cutaneous polyarteritis nodosa?
Recently described macular arteritis presents as asymptomatic hyperpigmented macules, runs a chronic, indolent course, and shows lymphocytic arteritis at various stages of evolution ranging from fibrinoid necrosis to endarteritis obliterans. Herein, we present another case that was clinically suspected to be unilateral plantar pompholyx. […]
Acquired cutaneous lymphangiectasia with mesothelial cells reflux in a patient with cirrhotic ascites.
A previously undescribed case of acquired cutaneous lymphangiectasias on the abdomen in a patient with cirrhotic ascites where peritoneal mesothelial cells refluxed in the skin is discussed. A 56-year-old man previously submitted to liver transplantation presented with vesiculobullous lesions on […]
Hematidrosis: a pathologic process or stigmata. A case report with comprehensive histopathologic and immunoperoxidase studies.
Cases of hematidrosis (bloody sweat) are extremely rare. This disease has been described in various terms and has been often tied to religious belief as stigmatization. We report a typical patient with hematidrosis in a 14-year-old girl who […]
