TEMPI syndrome: A clinical, light-microscopic and phenotypic evaluation with review of the literature

BACKGROUND AND OBJECTIVES

TEMPI (telangiectasias, elevated erythropoietin and erythrocytosis, monoclonal gammopathy, perinephric fluid collections, and intrapulmonaryshunting) syndrome is a rare multisystemic disease classified as a monoclonal gammopathy of cutaneous significance. The pathogenesis and etiology of TEMPIare not well known because of the rarity of this disorder. Although telangiectasias are the hallmark of this syndrome, skin biopsies are rarely performed. We aim to further characterize TEMPI syndrome through the evaluationof a skin biopsy.

METHODS

We reviewed the histopathology and immunophenotypic profile of a skin biopsy from a 53-year-oldwoman diagnosed with TEMPI syndrome. Other components of her syndromic complex included an IgA myeloma, elevated vascular endothelial growth factor (VEGF), and erythrocytosis.

RESULTS

A biopsy showed prominent vascular ectasia with some degree of microvascular basement membranezone thickening. Our patient had a reduction in neoplastic plasma cell burdenand clearing of her telangiectasias following myeloma directed treatment.

CONCLUSIONS

TEMPI can beviewed as a reactive vascular paraneoplastic syndrome in the setting of a plasma cell dyscrasia. Elaboration of VEGF from neoplastic plasma cells is likely pathogenetically implicated and appears to be a common link that explains other vascular lesions associated with monoclonal gammopathy syndromes.

Primary cutaneous acral CD8-positive T-cell lymphoproliferative disorder: A clinical and histologic retrospective cohort study

Clonally restricted, non-epidermotropic, low-grade, CD8-positive T-cell infiltrates of the skin was recognized as a unique form of indolent CD8-positive lymphoproliferative disease in 2007 when it was first called primary cutaneous indolent CD8-positive lymphoid proliferation. More recently, the designation of primary cutaneous acral CD8-positive T-cell lymphoproliferative disorder has been used. It is unique as a cutaneous lymphoproliferative disorder because of relative uniformity in its clinical presentation and histomorphology. It has been recognized as having an interesting predilection for the ear and acral sites, characteristically presenting as a solitary lesion. The basic morphology is one characterized by a non-epidermotropic, tumefactive infiltrate of well-differentiated, noncerebriform, atypical, small- to intermediate-sized lymphocytes that exhibit a specific phenotype characterized by CD8 and TIA positivity in concert with a distinct perinuclear Golgi staining pattern for CD68. The typical presentation is in the context of a solitary lesion, which can be treated surgically or with local irradiation. We describe in detail two very unusual cases that expand the clinical spectrum of this condition given the non-acral localization, the multiplicity of lesions to involve the trunk and extremities, and, in one case, the stable but recalcitrant course over 30 years. In addition, the second patient developed paraneoplastic dermatomyositis. We also retrospectively review our database for other cases that represent the entity of primary cutaneous acral CD8-positive T-cell lymphoproliferative disorder and review the literature focusing on non-acral cases. Nomenclature evolution from its first recognition in 2007 to the present is discussed.

Human Polyomavirus 9-An Emerging Cutaneous and Pulmonary Pathogen in Solid Organ Transplant Recipients

IMPORTANCE

We describe the first report to our knowledge of cutaneous and systemic pathogenicity of human polyomavirus 9 in solid organ transplant recipients.

OBJECTIVE

Three solid organ transplant recipients developed a widespread, progressive, violaceous, and hyperkeratotic skin eruption. All died from pulmonary and multiorgan failure around 1 year from onset of the rash. Routine clinical diagnostic testing could not identify any causative agent; therefore, samples and autopsies were investigated for novel pathogens using high-throughput sequencing.

DESIGN, SETTING, AND PARTICIPANTS

This case series, including 3 solid organ transplant recipients who developed characteristic pink, violaceous, or brown hyperkeratotic papules and plaques throughout the body, was conducted at the Columbia University Medical Center. Lesional skin biopsies were collected from all 3 patients and subjected to high-throughput illumina sequencing for identification of microbial pathogens. Human polyomavirus 9 was identified in lesional skin biopsies. We subsequently collected ocular swabs, oral swabs, urine samples, and blood samples from patients, and organ tissues at autopsy in 1 patient. We investigated these samples for the presence of human polyomavirus 9 using in situ hybridization and quantitative polymerase chain reaction (PCR) assays.

MAIN OUTCOMES AND MEASURES

A description of the clinical and pathologic findings of 3 patients.

RESULTS

This case series study found that human polyomavirus 9 was detected in the skin biopsies of all 3 patients by a capture-based high-throughput sequencing method platform (VirCapSeq-VERT). Human polyomavirus 9 was also detected in blood, oral, ocular swabs, and urine by real-time polymerase chain reaction (PCR) assay. In situ hybridization and quantitative PCR assays were performed on the skin biopsies from 3 patients and lung autopsy of 1 patient, which showed the presence of human polyomavirus 9 messenger RNA transcripts, indicating active viral replication and pathogenesis in the skin and lungs.

CONCLUSIONS AND RELEVANCE

Human polyomavirus 9 was associated with the widespread cutaneous eruption. All 3 patients had progression of cutaneous disease, accompanied by clinical deterioration, pulmonary failure, and death. One patient underwent autopsy and human polyomavirus 9 was identified in the lungs and paratracheal soft tissue. These findings suggest that human polyomavirus 9 may be associated with cutaneous and possibly pulmonary infection and death in solid organ transplant recipients.

Post-COVID-19 vaccination IgA vasculitis in an adult

Leukocytoclastic vasculitis has been reported in the setting of COVID‐19 infection and post‐COVID‐19 vaccination. We report a case of IgA vasculitis (IgAV) post‐COVID‐19 vaccination, with immunoglobulin A (IgA) immune deposits in the skin and renal involvement. SARS‐CoV spike protein immunohistochemical staining was negative. IgAV with skin and renal involvement is a potential reaction to COVID‐19 vaccination.

The use of drug calendars for the diagnosis of cutaneous drug eruptions in the age of electronic medical records

A morbilliform drug eruption is the most common condition leading to a dermatology consultation for a patient in the hospital. Timing is an important diagnostic tool since the onset of a skin rash usually takes place within days-to-weeks of the start of the implicated drug. A comprehensive, thorough, and reliable drug history by the clinician is essential. Therefore, to assist in the task of determining the causative medication of a new skin rash in a hospitalized patient, the creation of a drug calendar is recommended. The development of an electronic version of the drug calendar offers several benefits over the manual version. As the use of electronic medical records continues to become the standard in medicine, the electronic drug calendar will serve as an invaluable tool for the diagnosis of drug hypersensitivity.

Epidermotropic CXCR3 positive marginal zone lymphoma: a distinctive clinical histopathological entity potentially originating in the skin; it does not always indicate splenic marginal zone lymphoma

Epidermotropic B cell lymphoma represents a rare form of marginal zone lymphoma presenting as a disseminated skin rash resembling pityriasis rosea. To date there are 8 reported cases. In addition to the widespread nature of the skin rash, there is a proclivity for spleen and bone marrow involvement raising consideration regarding its categorization as a systemic lymphoma. We present an 89-year-old man with epidermotropic B cell lymphoma, who presented with a pityriasis rosea-like skin rash. An initial diagnosis of diffuse large cell B cell lymphoma was made based on the extent of dermal-based large cell infiltration. However, after recognizing the epidermotropic component and the distinctive clinical presentation, a diagnosis of epidermotropic B cell lymphoma was rendered. There was minimal bone marrow involvement based only on flow cytometric analysis, but there was no apparent bone marrow or splenic involvement on routine light microscopic assessment. Remission was = achieved with single agent rituximab chemotherapy and the patient remained symptom free. The neoplastic CD20 positive epidermotropic B lymphocytes expressed CXCR3. Similar to the prior reported cases by the authors, the neoplastic cells expressed CXCR3, a chemokine whose organ and tissue specific ligands could contribute to its relatively indolent clinicalcourse.

Resident Rounds Part III: Case Report: Fatal Cryptococcal Panniculitis in a Lung Transplant Recipient

Cryptococcal panniculitis is a rare entity previously reported in only 13 solid organ transplant (SOT) recipients. Cutaneous cryptococcosis in SOT recipients warrants extensive systemic workup and treatment as if central nervous system (CNS) disease is present. It should be included in the differential diagnosis of panniculitis in the immunocompromised host, as early diagnosis and treatment are critical. We report a fatal case of cryptococcal panniculitis in a 44-year-old lung transplant recipient.

Generalized verrucosis in a patient with GATA2 deficiency

Generalized verrucosis is a characteristic of several genetic and immunodeficiency disorders including epidermodysplasia verruciformis; warts, hypogammaglobulinaemia, infections and myelokathexis (WHIM) syndrome; warts, immunodeficiency, lymphoedema and anogenital dysplasia (WILD) syndrome; severe combined immune deficiency and HIV, among others. In recent years, it has been consistently recognized in patients with GATA2 deficiency, a novel immunodeficiency syndrome characterized by monocytopenia, B-cell and natural killer-cell lymphopenia, and a tendency to develop myeloid leukaemias and disseminated mycobacterial, human papillomavirus (HPV) and opportunistic fungal infections. Mutations in GATA2 cause haploinsufficiency and track in families as an autosomal dominant immunodeficiency. GATA2 is a transcription factor involved in early haematopoietic differentiation and lymphatic and vascular development. We describe a case of generalized verrucosis with HPV type 57 presenting in a young man with GATA2 deficiency. GATA2 deficiency is a novel dominant immunodeficiency that is often recognized later in life and should be considered in the differential diagnosis of patients with generalized verrucosis.

Persistent serpentine supravenous hyperpigmentation--a possible cutaneous manifestation of HIV infection or a normal racial variant: a report of 3 cases

Persistent serpentine supravenous hyperpigmentation (PSSH) describes a hyperpigmentation of the skin overlying peripheral veins. This cutaneous finding is typically seen in association with systemic chemotherapy or collagen vascular diseases such as progressive systemic sclerosis, systemic lupus erythematosus, and rheumatoid arthritis. Three dark-skinned patients with idiopathic serpentine supravenous hyperpigmentation (ISSH) without collagen vascular disease or prior intravenous cytotoxic treatments were reported. All 3 patients were dark-skinned men with symmetric, uniform hyperpigmentation of the supravenous network of the bilateral lower extremities that had been present for years. The serpentine supravenous hyperpigmentation on the lower extremities was uniform in width and color, which contrasts with the darker discoloration near the site of infusion seen with PSSH associated with chemotherapy. Interestingly, 2 of the patients had advanced human immunodeficiency virus (HIV) disease in association with their ISSH while the HIV status of the third patient was unknown. Thus, we contend that ISSH be considered a normal racial variant or a possible cutaneous manifestation of HIV disease.

Cutaneous angiosarcoma with skin metastases and persistent bloody pleural effusions

Cutaneous angiosarcoma is a rare aggressive malignancy of vascular origin that usually arises in the scalp or face of elderly men. We describe a case of primary cutaneous angiosarcoma with skin metastases and presumed metastases to the lung in a 58-year-old man who presented with persistent bloody pleural effusions, an asymptomatic nontraumatic red patch on the forehead of 2 to 3 months' duration, and a pair of purpuric papules on his left mid back of unknown duration. Cutaneous metastases of angiosarcoma are uncommon. Spontaneous persistent bloody effusions without hemoptysis are distinctly uncommon, and pleural fluid cytology is repeatedly negative in lung or pleural angiosarcoma, making it difficult to diagnose without tissue biopsy.

Drug hypersensitivity in the age of electronic medical records

Cutaneous drug eruptions are a common adverse reaction to medication. Creation of a drug calendar that covers a two-week span prior to the onset of rash is useful to identify the culprit agent. However, the creation of a drug calendar is often labor intensive. We developed an electronic version of a drug calendar that has considerably increased the ease and efficiency of completing a dermatology consultation.

Periumbilical parasitic thumbprint purpura: strongyloides hyperinfection syndrome acquired from a cadaveric renal transplant

Periumbilical parasitic thumbprint purpura may be a presenting sign of hyperinfection strongyloidiasis in the immunocompromised host. We report a case of fatal hyperinfection strongyloidiasis acquired from a cadaveric renal allograft, diagnosed by the pathognomonic periumbilical thumbprint purpuric eruption, confirmed by skin biopsy and laboratory testing.

Lichen planus of the esophagus: what dermatologists need to know

BACKGROUND

Esophageal lichen planus (ELP) is a rare manifestation of mucocutaneous lichen planus (LP).

OBJECTIVES

We aimed to report our experience and review all cases of ELP reported in the English-language literature.

METHODS

We report our experience with 4 cases and reviewed PubMed for reports of ELP. Cases were evaluated for age of onset, sex, location of LP, relationship of the onset of ELP to extra-ELP, endoscopic findings, whether biopsy was performed, histopathology of esophageal biopsy specimens, medical history (including gastrointestinal history), development of esophageal squamous cell carcinoma, therapies tried, and response to treatment.

RESULTS

A total of 72 cases of ELP were studied. In all, 87% of patients were female, with a median age of 61.9 years at time of diagnosis. Dysphagia was present in 81% and odynophagia was present in 24%. Oral LP was present in 89%, anogenital/vulvar LP in 42%, and cutaneous LP in 38%. Fourteen patients developed ELP as the sole or first manifestation of LP. Proximal esophageal lesions were present in 64%, distal in 11%, and both proximal and distal in 26%. Histology was "consistent with" LP in 71%. Four patients developed squamous cell carcinoma in association with ELP.

LIMITATIONS

This is a review of our cases and others reported in the literature.

CONCLUSIONS

ELP is underrecognized and underreported. There is often a significant delay between the onset of symptoms and the diagnosis. Malignant transformation of ELP to squamous cell carcinoma has been reported.

Cutaneous manifestations of Strongyloides stercoralis hyperinfection in an HIV-seropositive patient

A 41-year-old human immunodeficiency virus (HIV)-positive man was hospitalized with complaints of a 4-week history of nausea and vomiting, associated with decreased oral intake, and a 4-day history of frontal headache and fever. His medical history was significant for a gunshot wound to the head 3 years prior, with a residual seizure disorder. He also had two previous hospitalizations, both for culture-negative bacterial meningitis; the first episode occurred 12 months before admission and the second episode occurred 5 months later. At that time, he was found to be positive for serum antibodies against HIV and a CD4+ T-lymphocyte count of 126/mm3. He had no known drug allergies and was not receiving any medication. On admission, the patient was febrile (104.0 degrees F) and hypotensive (blood pressure, 92/40 mm Hg). Pertinent physical examination findings included cachexia with bitemporal wasting, dry mucus membranes, adherent white patches on the oral mucosa, and negative Kernig's and Brudzinski's signs. His laboratory results revealed macrocytic anemia, a decreased serum sodium of 125 mEq/L, and a normal total leukocyte count with a CD4+ T-lymphocyte count < 50/mm3. Lumbar puncture opening pressure was elevated at 160 mm Hg, and cerebrospinal fluid analysis showed an increased white cell count of 97/microL (84% lymphocytes), a decreased glucose level of 26 mg/dL, and a decreased protein level of 42 mg/dL. The patient was started on empiric therapy that included intravenous ampicillin and cefotaxime, oral Bactrim, and clotrimazole lozenges for thrush. Cerebrospinal fluid culture was positive for Escherichia coli, sensitive to cefotaxime. Two days later, the patient developed fine, erythematous, nonblanchable macules primarily on his abdomen, with minimal involvement of his thorax and back. His skin lesions remained unchanged for the next 2 weeks. Repeat lumbar puncture was performed after 14 days of cefotaxime. The cerebrospinal fluid analysis showed an elevated white cell count of 7/microL (100% lymphocytes), a decreased glucose level of 53 mg/dL, and a decreased protein level of 33 mg/dL. The cerebrospinal fluid culture was now positive for Pseudomonas aeruginosa resistant to cefotaxime. The patient was started on imipenem. On day 34 of his admission, the patient became tachypneic with complaints of dyspnea. A chest roentgenogram revealed bilateral patchy infiltrates. He was transferred to the intensive care unit and intubated for hypoxemic respiratory failure (arterial blood gas values on 6 L of oxygen: pH, 7.46; bicarbonate, 23; and oxygen saturation, 37). That evening, the patient was also noted to have diffuse petechiae and purpura in a reticulated pattern over his abdomen (Figure 1A and 1B), most heavily concentrated in the periumbilical region, extending to the axillae and upper thighs. A 3x3-mm punch biopsy from abdominal skin demonstrated Strongyloides stercoralis larvae in the dermis (Figure 2A and 2B). His sputum specimen was teeming with adult S stercoralis worms (Figure 3) and, subsequently, numerous S stercoralis larvae were observed not only from the bronchoalveolar lavage but also from the nasogastric fluid specimen. These findings confirmed the diagnosis of disseminated strongyloidiasis. On hospital day 35, the patient was doing poorly and was started on thiabendazole (1250 mg twice daily for 28 days). Nine days later, ivermectin (4.5 mg once daily for 3 days for 2 courses) was also added. He continued to clinically deteriorate. The patient died 31 days after systemic antihelminthic treatment was initiated.

Anti-laminin-332 mucous membrane pemphigoid associated with recurrent metastatic prostate carcinoma: hypothesis for a paraneoplastic phenomenon

Anti-epiligrin cicatricial pemphigoid is an autoimmune blistering disorder that has recently been associated with the development of solid organ malignancy. We describe a patient with recurrent metastatic prostate carcinoma who was diagnosed with this disorder. We provide a hypothesis as to the relationship between the development of this disease and its possible association with cancer pathogenesis.

An unusual cutaneous manifestation of Crohn's disease

A 61-year-old man with a 12-year history of quiescent Crohn's disease on mesalamine presented to his gastroenterologist in April 2009, complaining of abdominal cramping, diarrhea, and a 25-lb weight loss over 6 weeks. He did not respond to prednisone 50 mg and 6-mercaptopurine 100 mg daily. Abdominal computed tomography findings revealed diffuse submucosal edema consistent with extensive colitis. Colonoscopy demonstrated diffuse inflammation with erythema, friability, and shallow ulcerations in the rectum and colon. Biopsies were consistent with Crohn's colitis. He was admitted for infliximab infusion for his unremitting diarrhea. Five days before admission, the patient noted mild swelling and redness of the left lower eyelid, which progressed to involve the right lower eyelid with frank pus draining from both eyes. He had no visual impairment or eye pain. Two days before admission, an ophthalmologist prescribed a steroid eyedrop with no relief. He also complained of seropurulent painful skin lesions on his face and scalp, which spread to involve his upper trunk and proximal arms. On admission to the hospital, dermatology, ophthalmology, and infectious disease consultations were obtained to rule out disseminated infection before initiation of infliximab therapy. The patient was afebrile and hemodynamically stable. His oral mucosa was normal. He had prominent bilateral lower eyelid edema, erythema, and superficial erosions with hemorrhagic crusting and frank green purulent drainage from both eyes, with crusting along the lower lash line and bilateral sclera injection (Figure 1). On his scalp, face, trunk, and proximal extremities, he had 25 to 30 erythematous, 4- to 8-mm papulopustules with narrow red halos, some with central necrosis and crusting (Figure 2). Cultures from the purulent ocular drainage and pustules on the trunk and arms were all negative for bacteria, virus, and fungi. Gram stain from the eye drainage showed polymorphonuclear leukocytes without organisms. Tissue cultures were negative for bacterial, fungal, and mycobacterial infection. Skin biopsy taken from the central upper back demonstrated subcorneal pustules with areas of eroded epidermis and collections of neutrophils in the superficial dermis (Figure 3). Special stains were negative for organisms. He received infliximab infusion 5 mg/kg for a total dose of 420 mg over 2 hours. Within 48 hours of infusion, there was notable decrease in size of lesions, in addition to reduction of purulent drainage from both eyes. The patient was discharged home following infliximab infusion. His skin lesions resolved during a period of 2 weeks, leaving small pink atrophic scars. He received his second infusion of infliximab 2 weeks after discharge with continued improvement in his gastrointestinal symptoms.
