Such divi~ion is not cnlircly correct, for the pa ~hologic picture does not ahvays coincide with the dm ntion of thc process. Besidcs, more lhan one st.agc may exist at the samo time. Wtüle such a clat!sification is arbitrary, it is com·enient and oft.en helps to correlate the patho)ogic with the clinicsl picture. The pathologic picture of Kaposi&#39;s sarcoma shows new blood and lymph Yesscls, c·ellular elemcnts, connective tissuc hyperplasia t4nd hcmorrhage. The cellula.r elements include small round cells, wandering connective t issue cells, plasma cells, angjoblasts, spindle ceUs and fibroblasts. The proces:> is primary in the cutis; the epidermis shows no change unless secondarily in,·olved. The microscopic picture depends u pon the pha.se and t.ype of clinical Jesion examined. Any of the above features may predomi.nate and the seetion simulat.e such un- 1-elated dorrnatoses as angiomas, granulomas, apparently innocent innammatory l&#39;eact.ioos or highly ntalignant sarcomas. Before any of the features show pronounced prolirera.tion, t.he findings are those described by others in the early or inflammatory stage (fig. 3). 1&#39;he blood vessels of the upper and mid cutis are dilated, increased in number, frequently filled "·ith blood elcments, and arranged in groups or scattced diffuscly tbrough- • out thc cutis. Thc cndothelial cclls are S\VOllen and hs.ve Jarge v~ icular nuclei projecting into thc lumen (fig. 4). Thesc nuclei may be round and somewbat by~rc h1&#39;0ma tic, rathcr th.an oval and vesicular. Jnstead of being elongated, Lh~ cells may appear rectangular (cross-scdion of the cndothelial cell) and resemble somewhat the embryonic plasma ·oon of young granulat.ion t.issue. The lymph \&#39;essels and spaces ru&#39;() prominent. The cellular infiltration is sparse, perh·as<&#39;ular as well ns diffuse, s.nd composed of small round and wandering connect h·c tissue cclls, angioblnsts and sorne spindle oolls.

The pathologic changes in Ka.posi&#39;s sarcoma are in thc cutis. Vascular hyperpla&ia, hemorrh.age, angioblasts and spindle cells are found throughout the evolution of t.he disease except pcrhaps io the de,•elopment of spindle ooll sarcoma where the prolileration of spindle celhs overshadows all other features. Since tlte cytology is so important in thc microscopic di.agnosis of tbis di.::!ca.se, further discussion of some of thc ccllular clemcnts is warranted. This, we realize, • 322 THE JOURNAL Of&#39; JNVESTlGATlVE DERMATOLOOY is beset ";th many difficulties because o&#39;r inability to actually proYe contentions, and the vast differenc~ of opioion whioh exist umong authorities as to genesis, morphology and nomenclature. · Spituile oelts are found only in spindle cell sarcoma, or in a process which may eventua.te in sucb a sarcoma. We are led to bclieve th.at the sarcomatous process is not due to a simple accumulation of spindJe oolls from the parent cells, but ma.y depend on proliferation of these cells from otber spindle ceHs. The numerous rnitotic figures found in these cells would suhstantiate this view (fig. 10). The cytoplasrn of the spindle cell is scant and t he cell t.apers toa point at either end ; the nucleus is narrow, oval and vesicular with loosely arranged and lightly stained chromatin. The length of the cell is approximently twice Fw. lO. SeowiNO Sa&#39; JNDWO: CEa.us WITK MITOTIC F1o~; at ~S JS KAPOSJ &#39;8 SAl\COWA (700X) that of the nucleus. Wo doubt th.a.t this cell plays a.ny role in t.he production of collagen. Many different. types of cella, even epithelial cells, may ha. ve spiodle shspes; such oells sbould be refered to, notas spindle cells, but as spindle-shaped oolls. Thc relation of the jibrobla!lt to the spindle cell is un){nown. Contrary to the opinion of rnany, we believe that the two oells are different in. morphology, in function a.nd probably in derivation. The fibrobla.st is much larger in all dimensions and often has fiber-like projcctions extcnding from the tapering points. It ha8 an oval vesicular nucleus which is largcr and of greater diameter than the nucleua of t hc spindle cell. The fibt·oblast is approxirnently t,wo t.o throo times the size of the spindle cell. Unlike the spindle cell, the fibroblast doos forro collagen. 10l01&#39;A&#39;l&#39;lil(; Ht:MOIUUUGIC oRCO!\IA OF KAl&#39;OS The angiablast i.s thought to arisc from endotJ1elial cells and is referrcd to by sorne observe~ as an endothelioid cello Maximow and Blum (20) belicvc that the tenn o.ngiobla.st should not be used at allo Whilc the term endot.helioid cell ma.y be a.cceptable, \\&#39;e prefer to ret.aio the naroe angiobla.st because these cells are said to give rise to new vessels and because the mature cell usually does not resemble a.n endotheli.al cell. The angioblast has a round nucleus approximately H-2 times the size of the nucleus of a lymphocyteo It stains deeply, but the chromatin does not appear as a solid mass. As a rule, Jittle or no cytoplasm is observedo Bowever, a few of our sections show thc angioblasts with considerable cytoplasmo o Tbis is not unlike the polyhedral, pa.vcmcnt-like appearauce of endothelia.l oells when the flat surface is examinedo The origin of plasma ceU.s is stiU unset tled. lt is possible that they may be derh·ed fTom the endot helial cell or from an intermedia.ry cell which itself has arisen from a.n endothelial cell. The plasma. cell is acorn· or pear-shaped with sn eccentric nucleuso The chromatin of the oucleu.s is arran.ged a.t the periphery in several minute collections like the spokes of a wbeel. Tbe cytopl.asm is homogeneouso 1&#39;he cell is easily seen and recognized with the bematoxylin stain and only rarely are special sta.in.s necessary to determine th.e nature of the cello The shape of the plasma cell may differ from the uaual and occasionally appear round, rectanguhu or even spindle-shapedo Beside the common plasma cell, multinucleated or Moarsch.alko plasma cells ma.y be seen (figo 11). The derivation of the smallrou:nd cell is undeeidedo Some believe them to be related to lymphocytes, othen; do noto &#39;Ve a,re inclined to agree with tbe latter. The p~ence of small rouo.d cells in this process is a response t.o tissue injury a.nd is no different from their presence in ao.y ot.heto pathologic processo The morphology of the smaU round cell is different from that of th.e lymphocyte as seen in lymphat.ic leuk~mia.. The nucleus is more solid, irregular in sbape and size, and has no cytoplasm about ito Such cells are not seen in the circulating blood n.or in the lumen of vesselso o \Ve beUeve hem()rrhage is secondary rather than primary, and is th.e result of er~·throcytes waodering int.o the surrounding tissue from imperfectly formed new \&#39;essels or through ruptured or damaged \&#39;es...c;elso The proliferation of thinwalled vessels is thu to be considered the primary process and b.emorrhage is secondaryo DlFFERENTlAL DJAONOSIS Tl\e diseases to be considered in the differential diagnosis depend on the characteristic feature or features noted. The list of such diseases is long, and only the moro important will be discu..~d hereo In the early phases of Kaposi&#39;s sarcoma, before extensive hyperplasi.a has occurred, t he telangiectatic, the purpuric, the hemorrhagic and the simple inflammatory processes must be differentiatedo Tela.ngiectasia is not rclatod to hyperplasia of blood and l)rmph vesselso In hyperplasia, there are new vessels, especially capillaries; in tela.ngiect~sia, t.he picture is t.ha.t oí a dila.~ , t.ortuous vessel cut at many poiotso Ea.rly in the process, hemorrha.ge is not a difTerential point unless combined with other features of Kaposi&#39;s sarcoma: Most 324 TJfE IOQRNAL OP INVEST1GATIVE DERMATOLOOY important is a con ·ideralion of cylology, including plasma cells, angiobla.sts and spindle cells. These cells, vascular hyperplasia and hemorrhage are not. a part of a simple inftammatory process. A thorough st.udy and proper estimation of tbcse fcatures should lead to a correct. diagnosis. With definite hyperplasia of the vascular, connective tissuc or other ccllular clements, sorne of the graoulomas and neoplasms must be cxcludcd. Thc absence of epithelioid cell , giant cells and tubercles eliminates tuberculosis. Tbe presence of angioblasts and spindle cells plus the lack of vascular chnnges and plasma cell collarets rule out syphilis. Granulation tissue diffcrs in dcvelopment and e&#39; ·olution, ~rminates in complete fil>rosis, shows cells not seen in Kaposi&#39;s sarcoma, fibroblasts and plasma cells al&#39;e usually more abundant, angioblasts scarse and spindle cells are absent. 1\.mong the neopla.sms to be considered, Lhe most common and important are angioma, angiosarcoma, spindle ccll sarcoma, glomus tumor and granulom.a pyogenicum. Tho typical and usual angioma givcs little t rouble, but if cellular elements are also prcscnt the likcness may be striking. Thc ccllular elements are angioblasts and we believe that this iype of angioma is often referred to as endothcJioma or perithclioml\. There are msny, with whom we sgree, who seriously question the ex~nce of peritheliomas. We fecl that.they an;> angiomas associated ,,·ith aogioblasts. The diffcrential diagnosis of such angiomas, which are common in our c>.-perience, is cstablished by thc abscnce of hcmorrhage and spindle cells. Positive Perls&#39; reaetion (fig. 12) r plasma cells and incrcased lymphat.ic Yessels and spaces) is not present in angiosnrcoma. Without these feat.ures, the only way to diffcrentiate Ka.posi&#39;s sa.rcoma from angiosarcoma. may be the proper diagnosis of thc paront lesion. Spindle cell sarcoma. dc\&#39;eloping from a multiple idiopatbic hcmotThugic sarcoma <lillers littlo from the picturo of one not rclated to l{nposi&#39;s sarcoma. Al times, the pre3ence of angioblasts and plasma cells wili belp to C$tabli h the diagnosis. Differentiation is not difficult if corrobora.ting eddencc of Kaposi&#39;s sarcoma is present (fig. 13). Tho clinica.l picturc and history may he of considerable importante. Glomus tumor and gmnuloma pyogenicum are the most common ncoplasms to be differentiated from Kaposi&#39;s sarcoma. The microscopio diagnosi · of glomus tumor is comparat,ivcly simple on sections staiued with hematoxylin and eosin; we ñnd no need of special staios. Capillari~, even in the form of angioma.ta, are obscrved and about them is an intense uniform focal infiltration of a.ngioblasts; no othor cell.s are notcd. Although muscle and nerve t i.ssuc take part in the prooess, wo do not stress their presence. In clloically and microscopically provcn cases of Kaposi&#39;s sarcoma., we frequently find areas typical of glomus tumor and establish tho proper diagnosis onJy after careful study of the entire section. The vascular changes in granuloma pyogenicum are similar to those of Ka.posi&#39;s sarcoma, but the cytology is different. Angioblasts are nurocrous and diffusely arranged, but plasma cells are not conspicuous unless the lesion is secondarily io!ected, and spindle cells are not seen. Granuloma pyogenicum has little tendency to 6brosis.
