Panniculitis is a group of heterogeneous disorders characterized by inflammation of the subcutaneous adipose tissue. Panniculitis of breast tissue as the initial manifestation has rarely been reported and is often misdiagnosed. Breast panniculitis may cause substantial morbidity and early diagnosis and treatment are important for the prognosis of the disease. The present study has reported a case of panniculitis with inflammation of the mammary glands as the initial presentation and provided a detailed description of ultrasonography, X-ray, computed tomography, magnetic resonance imaging and other imaging features of breast panniculitis...

Dirofilaria repens is an endemic, zoonotic parasite of carnivores, causing subcutaneous dirofilariasis, which is mostly asymptomatic. The aim of this study was to describe 22 cases of canine subcutaneous dirofilariasis. The cytologic and histopathologic samples were collected from dogs, which presented with various clinical signs such as cutaneous/subcutaneous nodules, hydropericardium, ascites, and lymphadenomegaly. The cytologic or histopathologic examination revealed purulent, pyogranulomatous, granulomatous or eosinophilic dermatitis/panniculitis, and the presence of D repens microfilariae or adults...

AIMS: The diagnosis of cutaneous gamma delta T-cell lymphoma (GDTCL) requires the identification of γδ chains of the T-cell receptor (TCR). Using a new mAb to TCRδ, we evaluated TCRδ expression in formalin fixed paraffin embedded (FFPE) skin tissue from TCRγ-positive cutaneous T-cell lymphoma (CTCL) and assessed TCRδ expression within a spectrum of other cutaneous lymphoproliferative disorders (CLPD). METHODS AND RESULTS: 12 cases (10 patients) with TCRγ-positive CTCL and 132 additional CLPD cases (127 patients) were examined including mycosis fungoides (MF, n=60), cutaneous GDTCL (n=15), subcutaneous panniculitis-like T-cell lymphomas (SPTCL, n=11), and CD30+ lymphoproliferative disorders (CD30+LPDs, n=24)...

Protothecosis is a rare disease caused by environmental algae of the genus Prototheca. These are saprophytic, non-photosynthetic, aerobic, colorless algae that belong to the Chlorellaceae family. Seven different species have been described. Prototheca zopfii genotype 2 and P. wickerhamii are most commonly involved in pathogenic infections in humans and animals. The objective of this work is to describe, for the first time, a case of protothecosis caused by P. zopfii genotype 1 in a dog. The dog, a 4-year-old mix bred male, was presented to a veterinary clinic in Montevideo, Uruguay, with multiple skin nodules, one of which was excised by surgical biopsy...

Panniculitis is an uncommon skin eruption observed in patients with dermatomyositis (DM)/clinically amyopathic dermatomyositis (CADM), especially in anti-melanoma differentiation-associated gene 5 (MDA5) antibody-positive DM. We present here a 51-year-old Japanese woman with an anti-MDA5 antibody-positive DM who initially had cellulitis-like erythema on her right mandible. Histopathological findings showed a subcutaneous lobular infiltration of lymphocytes. The patient developed typical skin eruptions of DM/CADM, rapidly progressive interstitial lung disease, and severe muscle weakness 2 weeks after the first visit...

RATIONALE: Pancreatic pseudocyst can present single or multiple, inside or outside the pancreas. Pancreatic panniculitis is a rare skin lesion in pancreatic disease patients. The purpose of this study is to report a case of chronic pancreatitis coexisting with multiple pseudocysts and pancreatic panniculitis. PATIENT CONCERNS: A 46-year-old man with chronic pancreatitis presented multiple small cystic lesions inside the head of the pancreas and two large cystic lesions adjacent to the tail of the pancreas...

Composite lymphoma (CL) is a rare disease defined by the occurrence of 2 distinct lymphomas within a single tissue at the same time. We present the case of an 89-year-old male with a clinical history of immunoglobulin M monoclonal gammapathy of undetermined significance (IgM MGUS). The patient presented cutaneous eruption of nodules on the right bottom and arm. An excisional biopsy revealed cutaneous infiltration composed of 2 components. The first one consisted of large B-cell with CD20+/MUM1+/BCL2+ phenotype whereas the second one involved the subcutaneous fat in a panniculitis manner, was CD3+/CD8+/GranzymeB+/TCRβF1+...

Tongue worms utilise herbivorous mammals as intermediate hosts and reside in the nasopharynx of carnivores as their definitive hosts. A recent study in south eastern Australia showed an unexpectedly high infection (67%) of wild dogs with these parasites. The present study aimed at determining the pathogenicity of the parasite in both definitive (dog) and intermediate (cattle) hosts by histopathology. The definitive host showed multifocal haemorrhage of the interstitium of the nasal mucosa, multifocal mucosal erosion, congestion and haemorrhage, with haemosiderin laden macrophages present in those foci and distortion and destruction of the nasal mucosa...

INTRODUCTION: Extranodal natural killer/T-cell lymphoma (NK/T), nasal type, is an infrequent neoplasm with a high lethality, characterized by bone destruction around the sinus, nasal septum or obstruction of the airway. Also, may be primary skin involvement, airway and other organs. Objecti ve: Submit a rare condition in the pediatric population, in order to facilitate the diagnostic suspicion and quick recognition from specialists. CASE REPORT: a 14-year-old girl, who presented arm and leg lesions, painless, suggestive of subcutaneous panniculitis, which evolve to ulcerated purple maculae...

Erythema nodosum is a panniculitis associated with numerous diseases such as infections, inflammatory diseases, tuberculosis or can be idiopathic. We here report a case of a woman with erythema nodosum and reactive arthritis who was subsequently diagnosed with tuberculosis. A high level of suspicion and a thorough clinical and laboratory investigation of the patient presenting with erythema nodosum is required, in order to detect a possible systemic underlying condition.

The distinction between subcutaneous panniculitis-like T-cell lymphoma (SPTCL) and lupus erythematosus (LE) panniculitis is remarkably challenging. Rimming by lymphocytes with an elevated Ki-67 cell proliferation index has been forwarded as a potential diagnostic finding in biopsies of SPTCL but has not been rigorously compared with biopsies from patients with LE panniculitis. Nineteen and 17 examples of SPTCL and LE panniculitis, respectively, were evaluated for periadipocytic rimming by lymphocytes expressing Ki-67, CD8, and βF1 and for attributes associated with LE, including clusters of CD123-positive cells...

Pancreatic panniculitis is a rare type that only occurs in 2-3% of all patients with pancreatic diseases. It is usually described in association with benign pancreatic disease and less commonly in association with pancreatic carcinoma. We describe a case of pancreatic panniculitis as the first manifestation of underlying ampullary adenocarcinoma and a new case of pancreatitis, panniculitis and polyarthritis (PPP-Syndrome). Pancreatic panniculitis may be the cutaneous manifestation of pancreatic allograft rejection after simultaneous pancreas-kidney transplantation...

We report an unusual presentation in a 9-year-old girl with unilateral circumferential thinning of the entire right upper limb without any other neurological deficit, with normal nerve conduction and electromyography initially thought of as a neurodegenerative disorder based on clinical presentation. Magnetic resonance imaging of the upper limb showed partial lipoatrophy with normal glucose metabolism and lipid profile and negativity for HIV and autoimmune disease (panniculitis) with no family history of similar disorder...

BACKGROUND: Alpha-1 antitrypsin deficiency (AATD) may be associated with liver and lung disease and rarely causes panniculitis. OBJECTIVE: We evaluated the clinicopathologic and laboratory findings of AATD panniculitis in 10 patients. METHODS: We conducted a retrospective review of all cases of AATD panniculitis at Mayo Clinic, Rochester, MN, from 1989 to 2016. RESULTS: Ten patients with AATD panniculitis were included...

A late preterm infant presenting with supraventricular tachycardia (SVT) was admitted to the pediatric intensive care unit because of poor systolic function seen on echocardiogram. The hospitalization was complicated by multiple breakthrough episodes of SVT requiring ice placed on the face during each repeat episode. The infant was later diagnosed as having cold panniculitis secondary to the application of ice to the face on multiple occasions. In children who are hemodynamically stable during SVT episodes, ice is used as first-line treatment...
