1/26. panniculitis mimicking lupus erythematosus profundus: a new histopathologic finding in malignant atrophic papulosis (Degos disease).We present the case of a 57-year-old woman with a 1-year history of a cutaneous eruption clinically and histopathologically characteristic of Degos disease. In one of the two cutaneous biopsy specimens taken from the trunk lesions, the histopathology consisted of necrosis and sclerosis of the subcutaneous lobules, a finding that to our knowledge has not been previously described in the cutaneous lesions of Degos disease. Two months after cutaneous biopsies were taken, the patient developed ptosis and an episode of acute abdominal pain; intestinal perforation and many characteristic lesions of visceral Degos disease involving the entire small bowel were noted at laparotomy.- - - - - - - - - - ranking = 1keywords = abdominal pain (Clic here for more details about this article) |
2/26. methotrexate nodulosis.methotrexate (MTX) nodulosis in patients with rheumatoid arthritis treated with MTX has become a well recognized phenomenon. It has not been described in patients receiving MTX for treatment of other diseases, e.g., dermatological or malignant diseases. Recently, MTX nodulosis was described in a patient with psoriasis and arthritis. The pathophysiology and treatment of MTX nodulosis are yet unsettled. We experienced a case with dermatomyositis who developed multiple subcutaneous nodules after treatment with MTX. In our patient, numerous, small, symmetrically distributed, grouped subcutaneous nodules were seen on a V-shaped area of the anterior chest, both axillary areas, and the medial sides of both upper arms and thighs. We histopathologically examined a nodule and started treatment with hydroxychloroquine after discontinuation of MTX. The histopathology revealed septal panniculitis, and the nodules have been under regression. MTX nodulosis may be a drug-specific phenomenon. Discontinuation of MTX and replacement with hydroxychloroquine are recommended in severe cases. awareness of this entity is important for diagnosing and treating cases of multiple nodules developing after the administration of MTX, which is widely used for many dermatological diseases.- - - - - - - - - - ranking = 0.043057805123875keywords = chest, upper (Clic here for more details about this article) |
3/26. Subcutaneous panniculitic T-cell lymphoma and cytophagic histiocytic panniculitis.A 43-year-old Maori man presented with a 1 month history of malaise, weight loss, anorexia, arthralgia, recurrent fever and tender erythematous subcutaneous skin lesions. Histological examination of an incisional biopsy of a lesion revealed a lobular panniculitis with an inflammatory infiltrate of atypical lymphocytes and evidence of cytophagocytosis consistent with a diagnosis of subcutaneous T-cell lymphoma. The systemic symptoms and skin lesions resolved spontaneously within 3 weeks, only to recur 2 months later, requiring treatment with oral prednisolone. T-cell gene rearrangement studies demonstrated a monoclonal T-cell receptor (gamma-chain) gene rearrangement, further supporting the diagnosis of subcutaneous panniculitic T-cell lymphoma. Treatment with chemotherapy (cyclophosphamide, doxorubicin, vincristine and prednisone) led to remission of symptoms. Four months after completing chemotherapy, the patient remained asymptomatic with a few indurated subcutaneous plaques on the chest. biopsy of these areas revealed lobular panniculitis, lymphocytic infiltrate without cytological atypia, abundant lipophages and fibrosis and sclerosis consistent with a healing response. He remains well 24 months following chemotherapy.- - - - - - - - - - ranking = 0.025710067949062keywords = chest (Clic here for more details about this article) |
4/26. Pulmonary nocardiosis with bilateral diffuse granular lung shadows in a patient with subcutaneous panniculitic T-cell lymphoma.A 40-year-old woman undergoing prednisolone and cyclosporine therapy for subcutaneous panniculitic T-cell lymphoma complained of a cough for a few weeks. A chest X-ray revealed bilateral diffuse granular shadows. Additionally, the patient was discovered to have multiple subcutaneous abscesses. Gram-stained smears of sputum and pus from the abscess showing branched gram-positive rods led to a diagnosis of pulmonary nocardiosis with dissemination to the lungs and subcutaneous tissues. Combination therapy consisting of sulfamethoxazole/trimethoprim and panipenem/betamipron produced rapid improvement of radiographic abnormalities. It is suggested that pulmonary nocardiosis should be considered in the differential diagnosis of diffuse granular shadows on chest x-rays, especially in immunocompromised patients.- - - - - - - - - - ranking = 0.051420135898123keywords = chest (Clic here for more details about this article) |
5/26. panniculitis of the descending colon caused by enterocolic phlebitis: a case report.A 73-year-old male was referred to our hospital for abdominal pain, diarrhea and general fatigue lasting for 3 weeks. physical examination of the abdomen revealed a firm mass in the left abdominal region. Computed tomography revealed a mass around the descending colon. colonoscopy and barium enema revealed poor extensibility of the lumen with edematous mucosa, and narrowing of the descending colon with rugged mucosal surface. Because of the clinical symptoms and findings, the patient was diagnosed clinically as suffering from panniculitis of the descending colon. He underwent the left hemi-colectomy with side-to-side colo-colostomy after making of a loop ileostomy. Histological analysis of the resected colon showed an infiltration of inflammatory cells, predominantly lymphocytes, into veins and venules of the submucosa, muscularis propria and fat tissue of the colonic mesentery, with an involvement of all layers of the vessel wall. arteries were escaped from inflammatory changes. The histopathological diagnosis of enterocolic phlebitis and venulitis was made because of these findings.- - - - - - - - - - ranking = 1keywords = abdominal pain (Clic here for more details about this article) |
6/26. Pancreatic panniculitis in a patient with an acinar cell cystadenocarcinoma of the pancreas.We describe a 60-year-old man with pancreatic panniculitis associated with arthritis and peripheral eosinophilia in whom the skin symptoms led to a diagnosis of an underlying acinar cell cystadenocarcinoma. The panniculitis involved initially the legs, but soon thereafter lesions developed on the trunk and upper extremities. In the literature, only 5 cases of pancreatic acinar cell cystadenocarcinoma have been reported, none of these in association with panniculitis.- - - - - - - - - - ranking = 0.017347737174813keywords = upper (Clic here for more details about this article) |
7/26. Munchausen's syndrome presenting as severe panniculitis.factitious disorders may trouble any physician during his/her career. A considerable number of cases of Munchausen's syndrome (self-induced disorder) are misdiagnosed in clinical practice. A 36-year-old woman was admitted to our hospital because of fever and abdominal pain. physical examination showed signs of inflammation of the abdominal wall, and histological examination revealed severe panniculitis. We investigated various aetiologic factors that could probably be related to fat necrosis, but we found no explanation of the phenomenon until we verified the diagnosis of Munchausen's syndrome. 2 years later, the patient underwent surgery for removal of needles, which she herself had deliberately located under her skin. High index of suspicion and physician's persistence are necessary to make the correct diagnosis in the various protean manifestations of Munchausen's syndrome.- - - - - - - - - - ranking = 1keywords = abdominal pain (Clic here for more details about this article) |
8/26. Fine-needle aspiration of subcutaneous panniculitis-like T-cell lymphoma.We report the fine-needle aspiration (FNA) cytology findings of Subcutaneous panniculitis-like T-cell lymphoma (SCPTCL) in a 66-year-old woman who presented with a four month history of asymptomatic subcutaneous nodules on her right chest wall and back. An excisional biopsy of the right chest nodules was performed, and the diagnosis of SCPTCL was rendered. On a follow-up visit, several skin lesions were noted throughout her body. A fine-needle aspiration (FNA) of the right inguinal region was performed. The FNA yielded cellular smears, composed mainly of sheets of epithelioid histiocytes and scattered multinucleated cells. However, no distinct granulomas were noted. The background of the cytological smears showed scattered atypical lymphoid cells, some of which displayed nuclear membrane irregularities. To the best of our knowledge, the cytological features on FNA material of SCPTCL have not been described.- - - - - - - - - - ranking = 0.1285449880358keywords = back, chest (Clic here for more details about this article) |
9/26. Small vessel vasculitis and relapsing panniculitis in tumour necrosis factor receptor associated periodic syndrome (TRAPS).case reports: A 66 year old female patient had relapsing fever and non-suppurative panniculitis suggestive of enigmatic "Weber-Christian disease" (WCD). Antineutrophil cytoplasmic antibodies with specificity for human leucocyte elastase (HLE-ANCA) were detected. A biopsy showed small vessel vasculitis and panniculitis. A 53 year old man had recurrent episodes of abdominal pain, erythematous rash, and myalgia. Fever attacks had stopped a few years ago. A biopsy showed panniculitis and fasciitis. In both patients mutations (R92Q, T50M) of the tumour necrosis factor receptor super family (TNFRSF) 1A gene were disclosed. Mutations of the TNFRSF 1A gene are the cause of tumour necrosis factor receptor associated periodic syndrome (TRAPS). Both patients responded favourably to treatment with the human soluble p75 TNF alpha receptor fusion protein etanercept (2 x 25 mg subcutaneously/week). DISCUSSION: Small vessel vasculitis and panniculitis have not been reported in TRAPS so far. The cases underline the importance of TNF alpha regulation in inflammatory processes including vasculitis. Genetically determined causes of fever may account for some cases of WCD.- - - - - - - - - - ranking = 1keywords = abdominal pain (Clic here for more details about this article) |
10/26. From circumscribed scleroderma (morphea) to subcutaneous panniculitis-like T-cell lymphoma: case report.Subcutaneous panniculitis-like T-cell lymphoma is a rare form of non-Hodgkin lymphoma. It presents clinically as panniculitis, with erythematous, firm subcutaneous infiltrates and recurrent papulonodules. A 45-year-old male Croat presented with a 6-month history of tender erythematous subcutaneous skin lesions without systemic symptoms. Analysis of a lesion biopsy specimen showed circumscribed scleroderma (morphea). During hospitalization, skin biopsies from two subcutaneous lesions on the stomach were repeated, and pathohistologic analysis corresponded primarily to panniculitis in the context of morphea. Pathohistologic analysis and immunohistochemistry of a specimen obtained by tumor excision from the back indicated subcutaneous panniculitis-like T-cell lymphoma. Histologic analysis revealed a dense infiltrate of atypical T-lymphoid cells expressing CD8( ) phenotype located in the subcutaneous tissue with histiocyte-phagocytizing apoptotic cells. Specific hematologic analysis and medical treatment were continued. This case report illustrates the importance of continuous follow-up with repeat biopsy and use of immunohistologic techniques for early diagnosis.- - - - - - - - - - ranking = 0.038562426068837keywords = back (Clic here for more details about this article) |
