The histiocytes are CD68+.299 Surprisingly, in one series, the histiocytic component of the infiltrate stained only for vimentin and lysozyme and not the other common histiocyte markers (HAM56, CD68 (KP1), Mac-387, and factor XIIIa).421 PGM1, the most specific histiocytic marker, is strongly expressed in all cases.422,423 Lymph nodes act as a scaffolding system and home for lymphocytes, monocytes, and histiocytes in the lymphatic system. In contrast, medullary sinus histiocytes in three additional lymph nodes were B1-negative and reacted with anti-T4, anti-M1, and anti-lysozyme. Increases may reflect proliferation of resident sinusoidal histiocytes or an increased influx of histiocytes via the afferent lymphatics. Cases of florid dermatopathic lymphadenitiscan be alarming at first glance, secondary to large numbers of histiocytes which replace significant areas of the lymph node. …  |  Increased numbers of histiocytes are present within the paracortical and subcapsular sinuses (arrows). 2.

Having had a number of such cases referred to our laboratory for immunostaining purposes, I thought it might be of interest to readers to briefly review the common differential diagnostic possibilities to keep in Aims —Strong thyroglobulin immunoreactivity within sinus histiocytes in a lymph node draining a papillary thyroid carcinoma was observed in a recent case. if one compares the germinal center macrophages and the primary tumour. Aims —Strong thyroglobulin immunoreactivity within sinus histiocytes in a lymph node draining a papillary thyroid carcinoma was observed in a recent case. The inciting event is usually an infection, and it is hypothesized that the histiocytic proliferation may result from exaggerated lymphokine production in an immunocompromised host. Sinus histiocytosis is a common feature in lymph node biopsies and is characterized by dilated lymph node sinuses containing variable numbers of histiocytes, with bland, indented nuclei and eosinophilic cytoplasm (Fig. This prompted the investigation of whether thyroglobulin immunoreactivity is common in regional lymph nodes in cases of thyroid malignancy. Benign proliferative lesions of phagocytic histiocytes include sinus histiocytosis with massive lymphadenopathy, the hemophagocytic syndromes including familial erythrophagocytic lymphohistiocytosis, Kikuchi's disease, and the various granulomatous lesions of lymph nodes.

The disease presents variable clinical course and prognosis depending upon whether there is uni­system or multisystem involvement. Lymph fluid from the fingers, for instance, works its way toward the chest, joining fluid from the arm. The T4 antigen was detected in some of the sinus histiocytes … Yellow-brown bodies were observed in the sinusoids of lymph node and histiocytes. However, histochemical stains revealed that the cytoplasm of virtually every histiocyte contained large amounts of polyethylene Figure 1 . This article deals with non-haematologic malignant, i.e. A feature common to the disorders in this spectrum is histiocytosis, which is the overgrowth of immune system cells called histiocytes. In addition, there is often some degree of inter-stitial fibrosis, and, as above stated, capsular-fibrosis. General. When a lymphadenopathy is determined by the expansion of the follicular centres, the smears show numerous centrocytes and centroblasts intermingled with small mature lymphocytes, … AKA hyalinized lymph node. Reactive histiocytic and dendritic cell infiltrates occur in response to diverse stimuli and in addition to causing lymphadenopathy, may be present unexpectedly in lymph nodes … This prompted the investigation of whether thyroglobulin immunoreactivity is common in regional lymph nodes in cases of thyroid malignancy. The pathophysiology of histiocytoses is thought to be uncontrolled immunologic stimulation of normal antigen-processing cells rather than malignant transformation. Nuclear atypia was present in these cells. Normal histiocytes originate from pluripotent stem cells, which can be found in bone marrow. 1 was finally not able to be examined by EM. The cells abnormally accumulate in one or more tissues in the body, which can lead to organ or tissue damage. Author information. Lymph nodes are small, ball-shaped hollow organs that are distributed throughout the human body’s reticulated immune system. Conclusions—Positive staining with antithyroglobulin occurs not uncommonly in sinus histiocytes in lymph nodes draining thyroid tumours. C, Higher magnification of the histiocytic infiltrate with karyorrhectic debris; some histiocytes have crescentic nuclei (arrowheads).  |  %PDF-1.2 %���� Histiocyte increases in lymph nodes under constant spontaneous antigenic or foreign material stimulation (e.g., mesenteric lymph nodes) must be differentiated from increases due to treatment.
