Case 1 was a 75-year-old Japanese man who presented with a poorly demarcated, dark-red nodule with a destructive defect in the center, measuring 3 cm × 2 cm on the right wing of his nose. The histological diagnosis was a common form of infundibular squamous cell carcinoma. Atypical neoplastic cells radiated from the wall of a follicular infundibulum. The majority of neoplastic cells were positive for AE1/AE3 and 34βE12. Cytokeratin 17 expression was seen in the suprabasal cells of the deeply situated neoplastic components...

Angiomyomatous hamartoma of lymph nodes (AMH-LN) is an uncommon benign proliferation of smooth muscle, blood vessels, collagenous stroma and adipocytes, most commonly affecting inguinal LN. A similar constellation of cell types constitutes various members of the perivascular epithelioid cell tumor (PEComa) family, including lymphangioleiomyomatosis (LAM) which can involve LN in women. Because some LN-LAM patients have tuberous sclerosis complex (TSC) and/or other PEComa family lesions, it is clinically relevant to distinguish LN-LAM from AMH-LN...

Clinical trials of intralymphatic immunotherapy (ILIT) have been performed to overcome the limitations of long-term therapy and the local or systemic hypersensitivity reactions in conventional allergen-specific immunotherapy, including subcutaneous or sublingual immunotherapy. Additionally, several animal studies of ILIT have been conducted in the form of translational or veterinary research. We conducted a literature review to examine the treatment efficacy and adverse effects of ILIT.

We review the morpho-functional basis of the different types of angiogenesis and report our observations, including the formation of angiogenesis-related secondary structures. First of all, we consider the following issues: a) conceptual differences between angiogenesis and vasculogenesis, b) incidence of angiogenesis in pre- and postnatal life, c) regions of vascular tree with angiogenic capacity, d) cells (endothelial cells, pericytes, CD34+ adventitial stromal cells of the microvasculature and inflammatory cells) and extracellular matrix components involved in angiogenesis, e) events associated with angiogenesis, f) different types of angiogenesis, including sprouting and intussusceptive angiogenesis, and other angiogenic or vascularization forms arising from endothelial precursor cells (postnatal vasculogenesis), vasculogenesis mimicry, vessel co-option and piecemeal angiogenesis...

Residual carcinoma confined to lymphovascular spaces following neoadjuvant chemotherapy (NAC) for invasive breast carcinoma is an uncommon finding. We studied pathologic features and outcome for patients with pure intralymphatic carcinoma (PIC) following NAC, a pattern of residual disease reported to have a poor outcome in the only previously published series of this entity. Six of 284 (2.1%) patients treated with NAC were studied. All 6 patients had axillary lymph node involvement before NAC. Tumors were triple-negative (n=3) and HER2+ (n=3: 2 ER+, 1 ER-)...

Mesenchymal stem cells (MSCs) have a large potential in cell therapy for treatment of inflammatory and autoimmune diseases, thanks to their immunomodulatory properties. The encouraging results in animal models have initiated the translation of MSC therapy to clinical trials. In cell therapy protocols with MSCs, administered intravenously, several studies have shown that a small proportion of infused MSCs can traffic to the draining lymph nodes (LNs). This is accompanied with an increase of different types of regulatory immune cells in the LNs, suggesting the importance of migration of MSCs to the LNs in order to contribute to immunomodulatory response...

In most cases, cutaneous metastases develop after the diagnosis of the primary internal malignancy has been established, but sometimes they can be discovered earlier or simultaneously. We describe a case of a 90-year-old woman who presented to the emergency room in poor general condition, with cutaneous lesions characterized by hot, infiltrated, violaceous and erythematous plaques involving the left chest wall. The clinical and histopathological findings were consistent with the recently described variant of inflammatory cutaneous metastatic carcinoma named carcinoma hemorrhagiectoides...

Intravascular accumulation of lymphocytes in any body site can raise concerns for a lymphoproliferative disorder, mainly intravascular lymphoma, leukemia, or a form of angiocentric lymphoma. We recently found an intravascular lymphocytic accumulation of non-neoplastic nature in a uterine cervix. The aim of the study was to define the frequency and the nature of this observation in the uterine cervix. Thirty cervical excision specimens including 23 cone biopsies and 7 hysterectomies were examined for the presence of intravascular accumulation of lymphocytes...

BACKGROUND: Sentinel lymph node (SLN) metastasis is a powerful predictor of survival in primary cutaneous melanoma. Lymphatic invasion (LI) may correlate with increased risk of SLN metastasis. Intralymphatic metastases, often difficult to detect on hematoxylin and eosin (H&E) stained sections, are readily identified with dual immunohistochemistry for melanocytic and lymphatic markers. METHODS: We used dual S100/D240 immunohistochemistry to detect LI in 125 melanomas from patients who underwent SLN biopsy and correlated LI with melanoma staging parameters and disease status...

Type-1 allergies are among the most chronic common diseases of humans. Allergen immunotherapy (AIT) is the only causative and disease-modifying treatment option besides allergen avoidance. Severe systemic adverse allergic reactions may be induced by every AIT treatment. Different approaches have been used to provide safer AIT preparations to lower or even totally overcome this risk. Areas covered: A structured literature recherche in Medline and Pubmed under inclusion of national and international guidelines and Cochrane meta-analyses has been performed aiming at reviewing clinical use of such approaches in AIT...

Mesenchymal stem cells (MSCs) are multipotent stromal cells with immunomodulatory properties. They have emerged as a very promising treatment for autoimmunity and inflammatory diseases such as rheumatoid arthritis. Previous studies have demonstrated that MSCs, administered systemically, migrate to lymphoid tissues associated with the inflammatory site where functional MSC-induced immune cells with a regulatory phenotype were increased mediating the immunomodulatory effects of MSCs. These results suggest that homing of MSCs to the lymphatic system plays an important role in the mechanism of action of MSCs in vivo...

PURPOSE OF REVIEW: Animal studies published within the past 18 months were assessed, focusing on innate and specific immunomodulation, providing knowledge of high translational relevance for human atopic and allergic diseases. RECENT FINDINGS: Allergic companion animals represent alternative models, but most studies were done in mice. Atopic dermatitis mouse models were refined by the utilization of cytokines like IL-23 and relevant skin allergens or enzymes. A novel IL-6 reporter mouse allows biomonitoring of inflammation...

Chronic lymphedema predisposes to develop malignant cutaneous tumors, including angiosarcoma, Kaposi's sarcoma and B-cell lymphoma. T-cell malignancy has rarely been associated with chronic lymph stasis. Here, we report a case of primary cutaneous anaplastic large cell lymphoma (pcALCL) with lymphatic spread associated with chronic lymphedema. The patient is a 56-year-old man who received orchiectomy and right inguinal lymphadenectomy for malignant seminoma 10 years ago, which led to prominent lymphedema of the right leg...

Several recent clinical trials reported that intralymphatic immunotherapy (ILIT) for some allergens, such as cat dander and pollen, induce tolerance more rapidly than conventional subcutaneous or sublingual immunotherapy, have a comparable duration of effect after only 3 injections, and do not provoke serious local or systemic reactions. However, the efficacy and safety of ILIT are using Dermatophagoides farinae (Df), Dermatophagoides pteronyssinus (Dp), and dog, which are indoor allergens that are commonly found globally, need to be evaluated...

Intralymphatic histiocytosis is a benign condition characterized by poorly defined erythematous plaques (sometimes forming a reticular pattern) as well as the presence of nodules and vesicles. Its etiology and pathogenesis appear to be related to chronic inflammation in the affected area, prior surgery, or systemic disease, particularly rheumatoid arthritis. We report on 2 new cases, both associated with joint surgery in the affected area and osteoarticular disease (primary synovial osteochondromatosis and rheumatoid arthritis)...

Allergic rhinitis is a common health problem in both children and adults. The number of patients allergic to ragweed (Ambrosia artemisiifolia) is on the rise throughout Europe, having a significant negative impact on the patients' and their family's quality of life. Allergen-specific immunotherapy (AIT) has disease-modifying effects and can induce immune tolerance to allergens. Both subcutaneous immunotherapy and sublingual immunotherapy with ragweed extracts/preparations have clear positive clinical efficacy, especially over pharmacological treatment, even years after the treatment has ended...
