Non-scarring alopecia of lupus erythematosus: A comprehensive review

BACKGROUND

Although non-scarring alopecia (NSA) is a frequent clinical finding in patients with systemic lupus erythematosus (SLE), it has been poorly described in the literature. It is considered a nonspecific sign in the current classification of skin lesions of LE. The aim of this study was to give an updated overview of the spectrum of NSA in LE patients, with emphasis on the clinical significance thereof.

METHOD

We conducted a review of the English literature using the PubMed-Medline database using the keywords "Alopecia" + "Lupus erythematosus". Publications describing LE patients with NSA were included.

RESULTS

Data for 237 patients from 27 publications were analyzed. Ninety-one patients had diffuse NSA, 43 had patchy NSA, 83 had lupus hair, 3 had alopecia of dermal cutaneous LE, and 17 had alopecia of linear and annular lupus panniculitis of the scalp. Patients with diffuse/patchy NSA and lupus hair shared the following features: strong association with systemic activity of LE, subtle clinical/trichoscopic signs of inflammation, histological aspect consistent with lesions specific to cutaneous LE, high likelihood of response to SLE therapy, and absence of progression to scarring alopecia. Association with SLE was rare in patients with dermal cutaneous LE or linear and annular lupus panniculitis of the scalp, and skin-directed therapies were most often effective. One patient of each subtype progressed to scarring alopecia.

DISCUSSION

Diffuse/patchy NSA and lupus hair may represent a topographic variation of a single entity specific for LE. Prospective studies are warranted to further document the clinical significance of this manifestation.

Kikuchi-Fujimoto disease preceded by lupus erythematosus panniculitis: do these findings together herald the onset of systemic lupus erythematosus?

Kikuchi-Fujimoto disease (KFD), also known as histiocytic necrotizing lymphadenitis, is a rare disorder that must be distinguished from systemic lupus erythematosus (SLE). Although a minority of patients with KFD develop SLE, most patients have a self-limited disease. Importantly, KFD can have skin manifestations resembling cutaneous lupus. Therefore, the diagnosis of SLE should be predicated on a complete rheumatologic workup and not on the constellation of skin disease and lymphadenitis. Nonetheless, as our exceedingly rare case illustrates, patients who do not initially meet diagnostic criteria for SLE require dermatologic follow-up. We present a young adult woman who had a remote history of KFD and later presented with combined features of discoid lupus and lupus erythematosus panniculitis (LEP). On subsequent rheumatologic workup, she fulfilled criteria for SLE. We discuss the differential diagnosis of both KFD and LEP and emphasize how strong communication among dermatologists and other healthcare providers is essential in the management of patients with KFD.

The involvement of T regulatory lymphocytes in a cohort of lupus nephritis patients: a pilot study

T regulator lymphocytes (Tregs) play a key role in the maintenance of immune tolerance and in the development of autoimmune diseases. Expression of Foxp3 is specific for Tregs, and can be used for the identification of these cells. This study investigated the variations of Tregs Foxp3+ in the kidney biopsies inflammatory infiltrate of different lupus nephritis classes compared to that of ANCA glomerulonephritis, acute tubulointerstitial nephritis and nephroangiosclerosis. Sections of paraffin-embedded tissue have been stained by immunohistochemistry with anti-CD3 and anti-FoxP3 antibodies. We find that the ratio of FoxP3+/CD3+ cells is significantly lower in patients with lupus nephritis class IV and in patients with vasculitides than in the course of nephroangiosclerosis, tubulointerstitial nephritis and lupus nephritis class V. The data presented herein demonstrate a decrease of FoxP3+ Treg cells in the inflammatory infiltrate of lupus nephritis, particularly during the most active phases of lupus nephritis, as observed in the course of a IV class nephritis.

Lupus Panniculitis with Combined Features of Dermatomyositis Resulting in Severe Lipoatrophy

An 11-year-old girl presented with a one-year history of multiple, hard, slightly painful subcutaneous nodules on her right cheek, upper arms, and buttock. Histology of a skin biopsy specimen showed a lobular panniculitis. Laboratory studies revealed positive ANA, anti-double strand DNA, and elevated muscle enzymes. She was diagnosed as having lupus panniculitis. During hydroxychloroquine treatment, erythema over knuckle joints developed. These unusual clinical and laboratory findings of panniculitis associated connective tissue diseases made it difficult to make a precise diagnosis. We report this unusual case of lupus panniculitis with combined features of dermatomyositis resulting in severe lipoatrophy.

[Lupus erythematosus panniculitis presenting as palpebral edema and parotiditis]

Lupus erythematosus panniculitis or lupus erythematosus profundus is characterized by inflammation of the deep dermis and subcutaneous tissue. It can occur in isolation or associated with chronic systemic or discoid lupus erythematosus. It usually consists of nodules and hardened subcutaneous plaques on the forehead, cheeks, proximal extremities, and buttocks. Periorbital and parotid involvement are rare and can lead to misdiagnosis. We present the case of a patient with lupus erythematosus panniculitis who presented with palpebral edema and involvement of the periocular fat and parotid gland.

Emergence of panniculitis and haemophagocytic syndrome in a patient with chronic systemic lupus erythematosus

Panniculitis rarely occurs in the course of systemic lupus erythematosus (SLE). When it occurs, it is thought to be mainly lupus erythematosus panniculitis (LEP). Here we describe a 32-year old Japanese woman with chronic SLE, who simultaneously presented facial lymphocytic lobular panniculitis and pancytopenia due to haemophagocytic syndrome. She showed several auto-antibodies against trilineage haematopoetic cells, an anti-cardiolipin antibody, and no evidence of viral infection, indicating that her haemophagocytic syndrome might be autoimmune-associated haemophagocytic syndrome. The panniculitis and haemophagocytic syndrome presented simultaneously, and these manifestations were dramatically improved with corticosteroid therapy; therefore, the lymphocytic lobular panniculitis could be linked to autoimmune-associated haemophagocytic syndrome in this case.

[A case of lupus erythematosus profundus followed by systemic lupus erythematosus presenting with severe intestinal involvement]

A 52-year-old female visited the outpatient department of Sapporo Medical University hospital in 1984 due to a refractory rash on the skin of the trunk. Histological findings of a skin biopsy specimen indicated a diagnosis of lupus erythematosus profundus (LEP). The eruption remained quiescent with moderate doses of prednisolone. In October 2003, she was suddenly admitted to our hospital with abdominal pain, fever and bloody stool. Lupus enteritis was diagnosed based on an elevated level of anti-DNA antibody, low complementemia and diffuse edematous change of the intestinal walls on CT scans. Although high doses of corticosteroids resulted in transient improvement, melena developed again on the 24th hospital day. Colonoscopy revealed deep ulceration at the rectum and a gastrografin enema indicated perforation. Accordingly, the involved rectum was resected and an artificial anus was constructed on the 50th hospital day. Examination of the resected specimen by microscopy showed that the ulceration approached at the depth of the subserosal layer with intense infiltration of inflammatory cells around the vessels. The pathogenesis of the rectal lesion might have been due to vasculitis associated with systemic lupus erythematosus (SLE). The disease did not recur under the administration of 10 mg of prednisolone daily until November 2004. Colonic function made a remarkably untroubled recovery after the artificial anus was closed in February 2005. The LEP was generally accompanied by a mild form of SLE. This case seemed to be rare in that SLE was associated with severe lupus enteritis and a refractory rectal ulcer developed from LEP. Patients with SLE and intestinal involvement should be carefully monitored in cooperation with a surgeon.

Coexistence of extensive calcification and membrano-cystic changes in lupus erythematosus panniculitis associated with systemic lupus erythematosus

We report a case of lupus erythematosus panniculitis with long-standing systemic lupus erythematosus. The patient developed widespread calcification and membrano-cystic changes in the subcutaneous tissue. There have been no reports of the coexistence of calcification and membrano-cystic changes in the literature. The mechanism for the coexistence of the calcification and membrano-cystic changes might be due to the degenerative changes in fat cells from local circulatory disturbance.

Lupus profond et myélopathie

BACKGROUND

We report a case of myelopathy during the course of lupus profundus that is unique to our knowledge.

CASE-REPORT

A 29-year-old woman had lupus profundus since 1999, initially associated with thrombopenia (28,000 platelets/mm3) treated with corticosteroids for 6 months. Several nodular eruptions occurred from 1999 to 2004. Antinuclear antibodies were positive at 1/320 to 1/640 and complement C4 fraction was low. While being treated with hydroxychloroquine for a recent flare-up of nodular lesions of lupus profundus, she complained of paraesthesia of the abdominal wall and of the upper and lower limbs, suggestive of a medullary lesion. MRI disclosed an image of acute myelitis at the level of the second cervical vertebra. High doses of corticosteroids were promptly administered intravenously (methylprednisolone bolus) followed by oral prednisone and hydroxychloroquine. Six months later the patient was free of neurologic or cutaneous symptoms.

DISCUSSION

In the literature, systemic signs are rarely associated with lupus profundus and myelitis has never been reported. Lupus myelitis is a vascular and/or demyelinating and usually segmental lesion of the spinal cord. Neurologic symptoms are those of acute rather than chronic or recurrent transverse myelitis. The prognosis is poor with frequent and severe functional sequelae. Treatment is mainly based on high-dose systemic corticotherapy alone or combined with cyclophosphamide. Our patient responded favourably to early methylprednisolone bolus followed by oral corticosteroids and antimalarial treatment.

CONCLUSION

Lupus profundus is classically of benign course with only cutaneous involvement, but it may sometimes be a sign of systemic lupus and in rare cases may be associated with severe complications.

The dynamism of cutaneous lupus erythematosus: mild discoid lupus erythematosus evolving into SLE with SCLE and treatment-resistant lupus panniculitis

We present a 47-year-old Caucasian female who initially presented with mild discoid lupus erythematosus that evolved into systemic lupus erythematosus with subacute cutaneous LE and treatment-recalcitrant lupus panniculitis. Conventional therapy with antimalarials, systemic steroids, azathioprine, cyclophosphamide, methotrexate, and pulse doses of methylprednisolone did not control the course of the disease. Cyclosporin-A treatment led to clinical improvement and maintained remission.

A case of lupus erythematosus profundus with unusual manifestations

We describe a 16-year old female with lupus erythematosus panniculitis with unusual manifestations. She had noted to have developed erythematous nodules and plaques in the right axilla and inguinal region at the age of one year. These lesions resolved gradually with scar formation. However, new lesions were noted at the same locations in the following years. Some of her lesions at the scalp and the left axillary regions developing within the last two years slowly enlarged showing an annular configuration and subsequently resulted in hair loss. The erythematous border of her lesion in the left axilla consisted of two parallel red lines. Histopathological and direct immunofluorescent findings were consistent with lupus erythematosus panniculitis. Similar clinical findings in the same locations were also observed in the mother.

Multiple dermatofibromas associated with lupus profundus

We report a 58-year-old Afro-Caribbean woman who presented with more than 20 dermatofibromas on the body particularly on the back, arms and legs. These developed spontaneously over the course of 5 years. She also had a long-standing 5 x 2-cm area of lipoatrophy on the right upper arm and a 2-year history of several inflammatory subcutaneous nodules developing on the upper chest and left breast. These were confirmed histologically as lupus profundus. Apart from a mild arthritis, she had no other markers for systemic lupus erythematosus and was systemically well. Multiple dermatofibromas are rare. There are around 30 reports of multiple dermatofibromas associated with systemic diseases. More than half of these cases were associated with systemic lupus erythematosus, with or without systemic steroid therapy and about one-third were associated with HIV infection. Although the mechanism is unknown, it appears that multiple dermatofibromas are associated with autoimmune diseases or altered immune states. This is the first case of multiple dermatofibromas associated with lupus profundus. The knowledge of such associations may contribute to the understanding of the pathogenesis of dermatofibromas, which is as yet unknown.

Lupus-like panniculitis in a patient with autoimmune polyendocrinopathy-candidiasis-ectodermal dystrophy (APECED)

Autoimmune polyendocrinopathy-candidiasis-ectodermal dystrophy (APECED) is a rare autosomal recessive disorder, characterised by a loss of self-tolerance to endocrine tissues, chronic candidiasis and ectodermal disorders. APECED is associated with mutations of a single gene, designated autoimmune regulator (AIRE). We describe a 31-year-old APECED patient with non-traumatic, cutaneous ulcers on both forearms with features of a lupus-like panniculitis. On admission to the ICU in September 2001, the patient suffered from a ketoacidotic, hyperglycemic coma and adrenal crisis due to an Enterobacter-cloacae sepsis, originating from multiple, necrotising deep cutaneous ulcers. These ulcers spontaneously developed on both forearms, some of which were just emerging, full blown or healing with scars. Histological examination showed signs of a scarring panniculitis and vasculitis. Immunohistochemistry and direct immunofluorescence with characterisation of immunoglobulin and complement-factor binding pattern revealed features of a lupus-like panniculitis. Sequence analysis of all 14 exons of the AIRE gene revealed a R257 X mutation in exon 6 resulting in a nonsense mutation at codon 257 confirming the diagnosis of APECED. Oral treatment with 60 mg/day corticosteroids for two weeks led to complete resolution of all ulcers. In conclusion, mutations in the AIRE gene may provide the genetic background against which additional factors can initiate an autoimmune process. Here, autoimmune panniculitis appears to be an associated feature of the APECED syndrome. Our findings support the use of immunosuppressive therapy for autoimmune disease components of the APECED syndrome.

Lupus profundus: not a benign disease

Lupus profundus is an unusual clinical variant of cutaneous lupus erythematosus that has previously been described as a benign disease that follows a mild course. This report describes the extent of disease and associated comorbidities in patients with severe lupus profundus and systemic lupus erythematosus. Four cases of lupus profundus are reviewed and their associated systemic disease complications are highlighted. All four patients fulfilled at least four of the 11 criteria for systemic lupus erythematosus. One patient suffered from severe facial disfigurement and Parry-Romberg syndrome. Two patients developed nonhealing ulcers on the scalp. All four patients had scarring alopecia as well as depressed areas over large areas of their body surfaces. All patients were resistant to conservative therapy, and required long-term aggressive therapy. Clinical depression secondary to disfigurement was a major problem in three patients. Extensive lupus profundus may be associated with more serious systemic disease and warrants aggressive treatment early on to prevent permanent disfigurement and its resultant psychological consequences.

Panniculitis. Part II. Mostly lobular panniculitis

The second part of our review of panniculitis summarizes the clinicopathologic features of the mostly lobular panniculitides. Erythema induratum of Bazin (nodular vasculitis) represents the most common variant of lobular panniculitis with vasculitis, although controversy persists about the nature of the involved vessels. Mostly lobular panniculitides without vasculitis comprise a series of disparate disorders. These include sclerosing panniculitis that results from chronic venous insufficiency of the lower extremities; panniculitis with calcification of the vessel walls such as calciphylaxis and oxalosis; and inflammatory diseases with crystals within the adipocytes such as sclerema neonatorum, subcutaneous fat necrosis of the newborn, and poststeroid panniculitis. Connective tissue diseases, such as systemic lupus erythematosus and dermatomyositis, pancreatic diseases, and alpha(1)-antitrypsin deficiency may also show a mostly lobular panniculitis with characteristic histopathologic features. Lobular panniculitis may also be an expression of infections, trauma, or factitial causes involving the subcutaneous fat. Lipoatrophy refers to a loss of subcutaneous fat due to a previous inflammatory process involving the subcutis, and it may be the late-stage lesion of several types of panniculitis. In contrast, lipodystrophy means an absence of subcutaneous fat with no evidence of inflammation and often the process is associated with endocrinologic, metabolic, or autoimmune diseases. Finally, cytophagic histiocytic panniculitis is the term that has been used to describe two different processes: one is inflammatory, a lobular panniculitis, and the other one is neoplastic, a subcutaneous T-cell lymphoma. The only common feature of these two different processes is the presence of cytophagocytosis in the lesions. (J Am Acad Dermatol 2001;45:325-61.)

LEARNING OBJECTIVE

At the completion of this learning activity, participants should be familiar with the pathogenesis, clinical manifestations, histopathologic findings, and treatment options for the most frequent variants of the lobular panniculitides.

Calcifying lupus panniculitis in a patient with subacute cutaneous lupus erythematosus: response to diltiazem and chloroquine

Lupus panniculitis has been reported to occur with a frequency of 2-3% in patients with lupus erythematosus (LE). It is most often reported in association with lesions of discoid LE. We describe a patient with subacute cutaneous LE who developed calcified nodules that were histopathologically consistent with lupus panniculitis. She was treated with a combination of chloroquine and diltiazem with a good therapeutic response. The addition of diltiazem may be beneficial in patients with calcified nodules of lupus panniculitis.

Lupus erythematosus profundus with unusual skin manifestation: subcutaneous nodules coexisting with eyelid plaques

A 71-year-old Japanese woman presented with erythematous plaques on the eyelids and subcutaneous indurations or nodules with or without overlying erythema on the hands, thigh, and leg. She also had oral ulcers, arthralgia and a low grade fever. Laboratory tests revealed an elevated titer of antinuclear antibody, an increased erythrocyte sedimentation rate and anemia. Skin biopsy specimens from the hand and thigh showed lymphocytic perivascular and periappendageal infiltrates and vacuolar alterations at the basement membrane zone of the skin appendages. Moreover, there was a dense lymphocytic infiltrate deep in the dermis with extension into the subcutaneous fat, which was compatible with the diagnosis of lupus erythematosus profundus. Although the biopsy specimen from the eyelid lesion did not contain the subcutaneous fat, the changes in the dermis were essentially the same as those of the hand and thigh. The eruption as well as the other symptoms promptly responded to oral prednisolone.

A fatal case of pancreatic panniculitis presenting in a young patient with systemic lupus

BACKGROUND

Subcutaneous fat necrosis associated with pancreatic disease is a rare event. The clinical cutaneous findings are non-specific erythematous nodules with central softening located predominantly on the lower extremities. The histopathologic features of these lesions are very characteristic and diagnostic.

METHODS

We present an unusual case of pancreatic panniculitis associated with lupus pancreatitis in a 21-year-old African American female. The patient presented with lower extremity skin nodules, arthralgia, and serositis prior to the diagnosis of systemic lupus and pancreatitis. The skin lesions progressed despite normalization of serum pancreatic enzymes. Following femoral vein catheterization for renal dialysis, she developed a large indurated area over the left lower quadrant, flank, groin, and upper thigh measuring 25 cm. She was treated with repeated debridement, tissue grafts, and hyperbaric oxygen because of a clinical suspicion of necrotizing fasciitis.

RESULTS

Examination of skin biopsies and debrided tissue revealed the pathognomonic features of pancreatic panniculitis without any evidence of necrotizing fasciitis. Organisms were not detected by tissue examination or microbiologic cultures.

CONCLUSIONS

This case illustrates the potential role of vascular trauma in the pathogenesis of pancreatic panniculitis.

Orbital infarction and melting in a patient with systemic lupus erythematosus

OBJECTIVE

To present a patient with systemic lupus erythematosus who developed infarction and melting of the orbit secondary to her systemic disease.

DESIGN

A case report.

PARTICIPANT

A 61-year-old white woman with a 5-year history of systemic lupus erythematosus.

METHODS

The patient presented with left orbital pain, limitation of extraocular movements, and a fistula from the ethmoid sinus to the upper eyelid. A detailed examination with computerized tomography, ultrasound, and a comprehensive medical evaluation with laboratory testing was performed. Histopathologic analysis with special stains of the orbital tissues was also performed.

RESULTS

Histopathologic examination of the biopsy specimens revealed the features of an inflammatory process involving the orbit, similar to a panniculitis. These include a lymphocytic reaction with a predominance of plasma cells, vasculitis with occlusion, and thickening of the vessel walls, necrosis, and hyalinization of fat.

CONCLUSION

This is a unique case in which infarction and melting of the entire orbital structures occurred in the presence of systemic lupus erythematosus. The underlying disease process is a lupus-related panniculitis. The authors stress that this is a very rare entity and that other diseases should be ruled out before entertaining this diagnosis.

Generalized lupus erythematosus profundus in a patient with genetic partial deficiency of C4

Lupus erythematosus profundus (LEP) is an unusual variant of cutaneous lupus erythematosus (CLE)that is characterized by chronic, recurrent inflammation of the subcutaneous tissue leading to fibrosis. It is found in the settings of both discoid and systemic lupus erythematosus. Generalized forms are extremely rare. We present a case of generalized LEP associated with genetic partial C4-deficiency.

Generalized lupus panniculitis and antiphospholipid syndrome in a patient without complement deficiency

Generalized chronic cutaneous lupus including lupus panniculitis in childhood is rare and usually occurs in the setting of genetic complement deficiencies. The association with antiphospholipid syndrome is even more rare. We report a 13-year-old girl with extensive lupus panniculitis since the age of 8 months and no evidence of complement deficiency. She recently developed antiphospholipid syndrome characterized by anticardiolipin antibodies and digital necrosis.

Lipomembranous (membranocystic) fat necrosis. Clinicopathologic correlation of 38 cases

Clinicopathologic correlation of cutaneous biopsy specimens demonstrating typical lipomembranous fat necrosis was performed. Material from 732 biopsies of various subcutaneous inflammatory disorders seen at our institution in the past 5 years was screened for typical lipomembranous (membranocystic) changes in the panniculus, and 39 specimens from 38 patients with these changes were identified. The most common clinical context in which this condition was observed was in chronic sclerotic plaques of the lower legs associated with venous insufficiency (37% of the total cases). All patients were women, and the majority were obese. Typical lipomembranous fat necrosis was also observed in eight cases (21%) of erythema nodosum, three (8%) of morphea or subcutaneous morphea (or both), two (5%) of lupus panniculitis, two (5%) of necrobiosis lipoidica, and in single cases of polyarteritis nodosa, necrotizing vasculitis, and erysipelas. Six cases (16%) had no definite underlying disease. The mean age of all patients was 57 years (range 32-86 years), and 34 patients (89%) were women. Of the five major categories identified, lipomembranes lining macrocysts and microcysts were most prominent in the venous insufficiency- and morphea-related cases and were much less prominent in erythema nodosum, lupus panniculitis, and necrobiosis lipoidica, which generally showed histopathologic findings typical of these disorders. In addition to lining the macrocystic and microcystic cavities formed in the fat lobules, lipomembranes were prominent in areas of septal fibrosis in all cases associated with morphea and necrobiosis lipoidica and in 35% and 25% of venous insufficiency- and erythema nodosum-related cases, respectively. In lupus panniculitis, lipomembranes were most prominent in areas of hyaline necrosis. We conclude that lipomembranous fat necrosis is most likely a nonspecific form of ischemic fat degeneration that may be induced by various clinical entities. This change is most often seen in venous insufficiency-associated chronic sclerotic plaques typically observed in middle-aged obese women, and we propose the term stasis-associated lipomembranous panniculitis (SALP) to describe this most common form of lipomembranous fat necrosis.

Lupus erythematosus profundus: a cutaneous marker for a distinct clinical subset?

Sixteen patients with histologically confirmed lupus erythematosus profundus were followed for a decade (on average). At the initial examination, two of 16 (12%) patients fulfilled the 1982 American Rheumatism Association (ARA) criteria for systemic lupus erythematosus (SLE). During the period of observation, SLE developed in another two (12%) patients, both of whom developed a malar rash. The remaining 12 (75%) patients never met the criteria for SLE. Four of the 16 (25%) had no extracutaneous manifestation. In conclusion, most patients with lupus erythematosus profundus have a relatively mild disease course, although a few develop systemic abnormalities and have abnormal laboratory findings.

Discoid lupus erythematosus lesions developed on lupus erythematosus profundus nodules

We describe this case of LEP for its unusual way of presentation. It first appeared with a LEP pattern, followed by a typical DLE of the skin, overlying the nodules only. Moreover, our histologic findings showed the typical pattern of lymphocytic lobular panniculitis, with hyaline necrosis of fat, the lymphoid nodule, and even the lymphocytic nuclear "dust." The epidermal changes, with the liquefaction degeneration of the basal cell layer, a moderate follicular hyperkeratosis, and a perivascular and periappendeal lymphocytic infiltrate, were also observed in the abdominal lesion that developed last without clinically evident DLE.

Membranous lipodystrophy: secondary type

BACKGROUND

A peculiar type of fat necrosis was noted in some patients with various skin diseases.

OBJECTIVE

We attempted to develop a classification of membranous lipodystrophy combining the results of our study and a review of other articles.

METHODS

Five cases of skin diseases with membranous lipodystrophy were studied and their clinical and histopathologic features were analyzed. Previous reports of similar findings were reviewed.

RESULTS

Membranous lipodystrophic changes were noted in morphea profunda, lupus panniculitis, and factitial ulcer. Microcysts were formed by the coalescence of the destroyed fat cells and were lined by amorphous, eosinophilic material. Some of the linings had a crenelated appearance. Microgranules were found in the histiocytes and in the hyalinized collagen stroma. The linings and microgranules stained positively with periodic acid-Schiff, were resistant to diastase, and also stained with Sudan black B.

CONCLUSION

We propose the use of the term secondary membranous lipodystrophy to describe the local subcutaneous membranous lipodystrophic change that occurs as a result of other skin diseases, in contrast to primary idiopathic membranous lipodystrophy, which occurs without any antecedent factors.

Lupus mastitis

We describe a woman with sclerotic and atrophic lesions of the breast. Histopathologic and immunologic findings indicated a diagnosis of lupus erythematosus. Lupus mastitis is a rare presentation of panniculitis; only a few cases have been reported in the literature.

[Systemic lupus erythematosus (SLE) with panniculitis and rhabdomyolysis]

In systemic lupus erythematosus as a multi-system disease the involvement of skeletal muscle has been described as a rather mild polymyositis, myopathy or inclusion-body myositis. Here we present a patient with a severe lupus presenting with a fulminant myositis with rhabdomyolysis and panniculitis.
