The authors observed a 66-year-old woman with a previous history of paresthesia of distal prevalence in the upper limbs and the lower right limb associated with pain in the palmar and plantar region, with onset 1 year before, followed by reduction in strength, mainly in hands and feet, of slow and progressive evolution. During this period the patient noted diffuse skin darkening and appearance of papular lesions on the cervical and right infraclavicular region, abdomen and dorsum. She suffered a 20-kg weight loss during evolution of the picture, besides diabetes mellitus and hypothyroidism. Examination showed diffuse cutaneous hyperpigmentation, atrophy of the interosseous muscles (fig. , fig. ), sclerodermiform cutaneous thickening and normochromic, papular lesions (fig. ) in the cervical region, abdominal and right infraclavicular region. At dermatoscopy of the infraclavicular lesions there was presence of red lakes (fig. ). Neurological examination showed grade 3 strength of distal prevalence in the upper and lower limbs and hypopallesthesia in ‘glove’ and in ‘boot’. These alterations were suggestive of sensorimotor polyneuropathy.\nOphthalmological examination did not reveal presence of papillary edema. Concerning laboratory examinations, thrombocytosis was noted, with rheumatoid factor <10; anti-nuclear factor, VDRL, anti-HIV, anti-HTLV and serology for hepatitis B and C were negative. Prolactin and cortisol dosages were within normal range. Electroneuromyography was compatible with polyneuropathy with predominance of demyelination and axonal degeneration. Bone marrow aspirate presented medullary plasmacytosis (9% plasmacytes). Serous protein electrophoresis demonstrated a monoclonal peak in the gamma fraction and in immunofixation examination: monoclonal IgG/lambda peak.\nSkeleton radiography revealed a lithic lesion with sclerotic borders in the left femur (fig. ); histopathologic examination confirmed it to be a plasmocytoma. Histopathologic examination of the right infraclavicular lesion showed an exophytic lesion containing dispersed vascular connective structures (fig. ), and increased magnification showed both thick- and thin-walled vascular structures, compatible with arteriovenous hemangioma (fig. ). The lesion on the dorsum presented histopathologic characteristics of hemangioma in tufts and the lesion on the abdomen cherry hemangioma.\nThe patient was treated with radiotherapy of the femur due to the osteosclerotic lesions and showed improvement of the neurological picture as well as of hyperpigmentation and weigh loss.
Woman, 65-year-old, with sensory-motor polyneuropathy for 15 years, worsening in the\nprevious 6 months. The patient had diffuse hyperpigmentation, dry skin and hemangiomas\n( and ). She reported hypertrichosis, edema of the legs, facial lipoatrophy,\nleukonychia and weight loss ( and ). Analytically, she presented polyglobulia,\nthrombocytosis, hypotestosteronemia, hyperalbuminemia and elevation of IgG in the\nliquor. The immunochemical study emphasized IgG monoclonal gammopathy of lambda\nchains.\nInvestigations showed small adenopathies, cardiomegaly, hepatosplenomegaly, generalized\nedema and extensive lytic lesion of L5. A biopsy of this lesion showed a lytic\nproliferation of plasma cells, CD138 +, К chains - chains λ +. The myelogram showed\nhypercellularity and eosinophilia. The electromyogram showed slowing of motor and\nsensory nerve conduction of several nerves. An excision of the right breast angioma was\nperformed and was compatible with capillary hemangioma. The patient has begun treatment\nwith dexamethasone, radiotherapy, bortezomib and is waiting for a bone marrow\ntransplant.
