1/16. Pseudoainhum of all fingers associated with Reynolds' syndrome and breast cancer: report of a case and review of the literature. Pseudoainhum is a rare disorder characterized by digital constrictions leading to autoamputation. We report a bilateral pseudoainhum of all fingers in a 64-year-old fair-skinned woman with breast cancer, systemic scleroderma, and primary biliary cirrhosis. The overlap between scleroderma and primary biliary cirrhosis with antimitochondrial antibodies M2 is also known as Reynolds' syndrome. Although pseudoainhum has been associated with many conditions, this particular association is exceptional and has yet not been described. ( info) |
2/16. Digital constriction bands in pseudoainhum: morphological radiographic, and histological analysis. Pseudoainhum is a rare condition of unknown etiology that produces digital constricting rings, most commonly on the small fingers. A thorough discussion of pseudoainhum in the plastic surgical literature is apparently lacking at this time. The authors describe the gross morphology, radiographic and laboratory features, and surgical pathology of the disease, and provide well-defined guidelines for its treatment. ( info) |
3/16. ainhum: treatment with intralesional steroids. ainhum is a rare constricting band disease, usually affecting digits and resulting in spontaneous amputation. Prompt symptomatic relief and latter partial resolution of the fibrotic band followed intralesional steroid injection in the case presented. ( info) |
4/16. Lamellar ichthyosis associated with pseudoainhum of the toes and eye changes. Classic lamellar ichthyosis is a rare, autosomal recessive, genetically heterogeneous skin disease caused by mutations in the transglutaminase 1 gene. Pseudoainhum is characterized by the appearance of a constricting band around a digit which may lead to spontaneous amputation. We describe a 41-year-old man with classic lamellar ichthyosis with unusual eye changes and pseudoainhum of both the fifth and the third right toes. eye abnormalities included bilateral ectropion of the lower eyelids, chronic blepharitis, and nuclear cataract. A radiometric assay revealed greatly reduced skin transglutaminase activity. To the best of our knowledge, this report is unique as classic lamellar ichthyosis with deficient transglutaminase activity has never been associated with pseudoainhum of the toes and the early development of nuclear cataract.

5/16. Pseudoainhum in chronic psoriasis. Pseudoainhum is a term used to describe the presence of constricting bands of the extremities due to a variety of underlying causes. Progression of the lesions can cause irreversible damage and autoamputation of the affected digit. This report documents a rare association of pseudoainhum and psoriasis and emphasizes the importance of recognizing this condition. ( info) |
6/16. Case report: ainhum (spontaneous dactylolysis) in a 65-year-old American black man. ainhum is the spontaneous autoamputation of toes as a result of the formation of a constricting band. It usually affects the fifth toe bilaterally and predominantly affects blacks in tropical regions, but has been uncommonly reported in temperate regions as well, including the united states. Of the 29 cases identified in the American literature since 1960, only 6 were published in the internal medicine literature. Because of the rarity of ainhum and consequent lack of attention in the clinical literature, this condition may be relatively unknown and therefore unrecognized by practicing internists. A patient with ainhum is described and the clinical features of this rare disease are emphasized to facilitate recognition and appropriate management. ( info) |
7/16. Pseudoainhum in porokeratosis of Mibelli. porokeratosis of Mibelli in an adult man with involvement of the skin and oral and genital mucous membranes is described. The unusual features in this case were the late onset and pseudoainhum resulting from a porokeratotic lesion in the right foot. The probable cause of pseudoainhum is reviewed. ( info) |
8/16. Dactylolysis spontanea or ainhum involving the big toe. We describe the case of an Italian Caucasian man with ainhum involving both big toes. ainhum or dactylolysis spontanea is characterized by the development of a constricting band around a toe, which progresses to spontaneous autoamputation. It usually affects the fifth toe bilaterally, but in rare cases other toes may be involved. The disease occurs in Black people living in tropical regions but occasionally has been reported in persons having fair skin. ( info) |
9/16. The surgical pathology of ainhum (dactylolysis spontanea). ainhum (dactylolysis spontanea) is a poorly understood disease characterized by spontaneous autoamputation of the fifth toe. Its incidence is highest among blacks and in the tropical and subtropical climates. The present study is the first to present certain gross and semimicroscopic findings. Moreover, scanning electron microscopic and histochemical data are presented and these reportings are believed to be unique. Hyperkeratosis and parakeratosis, together with elongation of the epidermal rete pegs and acanthosis, are observed and these findings are associated with the presence of numerous fibroblasts and wound repair phenomena. The leukocytic infiltrate is identified as being principally of T lymphocyte type, suggesting the existence of an unknown immunologic response. Relevant intraoperative data, radiographs, and light microscopy, as well as transmission electron microscopy, have been reported in this study. The spontaneous amputation of the fifth toe, designated as dactylolysis spontanea, has no known etiology, and no treatment short of amputation. The worldwide incidence of this condition is rare. Two cases have been observed at the baltimore veterans Administration Medical Center in the last 5 years. One patient is in an early stage of the disease. The present study involves the single instance in which amputation was elected as the treatment of choice. Because the occurrence of ainhum (dactylolysis spontanea) is rare, discussion of the disease is lacking in medical literature. It is the intent of the present study to be the definitive analysis of clinical, surgical, and surgical-pathologic data of this rare disease. Unique applications of semimicroscopic, histochemical, and light microscopic findings, as well as transmission and electron microscopy, will be presented. Speculation as to the implications of immunologic and/or wound repair responses as implicated in ainhum needs to be explored. ( info) |
10/16. Pseudoainhum and erythropoietic protoporphyria. We report the development of pseudoainhum in a patient with erythropoietic protoporphyria, the first report, to our knowledge, of these two unusual conditions occurring together. An excellent cosmetic and functional result was achieved with a Z plasty. ( info) |
