HOW TO FIND ........... ?
First question:
How can you find all the pathological changes on a specific topographic location, the bronchus, for example, cumulated during 1989-2009 ?
Answer:
Bronchus belongs to the respiratory system. Thus, see the first stratum of classification of the topography of histopathological findings, where all systems are presented and where, in row 03, you can see that this system covers 5 % (13.269) of all findings (for 1989-2009). You can reach the first stratum by clicking the corresponding hyperlink on the home page, in the abbreviated contents, in the contents or here.
To get the second stratum of classification of the respiratory system click the hyperlink "respiratory system". There, all the localizations inside respiratory system can be found. The localization bronchus is in row 1621-00. This row shows that 79 % of all the findings ( 10.438) in the respiratory tract belong to the bronchus.
Clicking the hyperlink "bronchus", the third stratum of classification is reached, where all histopathological changes of bronchus are shown. It could be seen that the most numerous are the findings with chronic inflamation (4300-00) - 23 % (2.365). They are followed by bronchial epidermoid carcinoma (8073-03) -25 % (2.561), and small cell bronchial carcinoma (8043-01) - 13 % (1.380).
Second question:
How can you find all the various localizations of a specific histopathological change, such as tuberculosis (caseating granuloma), cumulated during 1989-2009 ?
Answer:
Tuberculosis is an inflammatory process. Thus, start with the first stratum of SNOP classification of morphology, clicking the coresponding link on the home page, in the abbreviated contents, in the contents or here, where the inflammation and fibrosis are at row 04. You can see that 16 % (41.782) of all findings belong to those pathological processes.
Click the hyperlink "inflammation and fibrosis", where all types of inflammation can be found in the second stratum of classification. Tuberculosis or Caseating Granuloma is in the row 4470-00. There it can be seen that 697 patients with tuberculosis represent 2 % of all inflammatory processes. Clicking the hyperlink "Caseating granuloma" the third stratum is reached.
In the reached third stratum all localizations of tuberculosis are listed. The most frequent localization is /1621-00/ bronchial tuberculosis (14 % or 97 findings), followed by tuberculosis of cervical lymph nodes /1960-02/ (13 % or 88 findings). Laryngeal tuberculosis /1619-00/ is also very frequent (11 % or 75 findings), followed by pulmonary tuberculosis /1620-02/ (5 % or 34 findings ).
Third question:
How can you find all the various cytologicaly predicted (after FNAB - Fine Needle Aspiration Biopsy) pathological changes at a specific topographic location, for example thigh?
Answer:
Thigh belongs to the soft tissue. Thus, reach the first stratum of classification of FNAB cytological findings clicking the coresponding hyperlink on the home page, in the abbreviated contents, in the contents or here , where all topographic systems are presented and where, at the row 09, it can be seen that soft tissue covers 9 % (or 16.158 findings) of all the findings in 1989-2009.
The second stratum of classification is reached clicking the hyperlink "soft tissue" There all localizations inside the soft tissue system can be found. The localization thigh is in the row 1713-03. It can also be seen that during 1989-2009, there were 835 (5 %) aspiration biopsies of the thigh, 120 (15%) positive and 713 (85%) negative.
The coding of the morphology of cytological findings was introduced in 1993. That is why the various expected diagnoses are available only for the period 1993-2008.To reach the third stratum click the hyperlink "thigh". There it can be seen that the most frequent benign pathological change is 8850-00 lipoma (172 findings or 21 %). Among positive cytologic findings most frequent pathological changes on this localization are fibrosarcoma (9) and malignant fibrohistiocytoma (8)
Fourth question:
How can you find, all the various localizations of a specified predictive cytological diagnosis (after FNAB), for example, tuberculosis, cumulated during 1993-2008?
Answer:
Tuberculosis is an inflammatory process. Thus, start with the first stratum of SNOP classification of cytological morphology, clicking the coresponding hyperlink on the home page, in the abbreviated contents, in the contents or here, where the inflammation and fibrosis are in row 04. It can be seen that 23% of all the findings (or 42.570of FNAB cytologycal findings) belong to these pathological processes.
All
types of inflammation can be found in the second stratum of
classification reached clicking the hyperlink "Inflamation and fibrosis"..
Tuberculosis or Caseating Granuloma is in the row 4470-00. There it can be seen
that 742 patients with tuberculosis represent 2 % of all
inflammatory processes. The third stratum of classification is
reached, showing the various localizations of caseating granuloma, clicking
the hyperlink "Caseating
granuloma".
In the third stratum all the localizations of tuberculosis are listed. The most frequent localization is /1960-02/ cervical lymph node (435 or 59%). Also, very frequently encountered localizations are /1960-16/ supraclavicular nodes (105 or 14 %) and /1963-01/ lymph nodes of axilla (67 or 9 %). 82 % of all tuberculosis is found in those three groups of lymph nodes.
Fifth question:
How can you find all the various topics in the Atlas ?
Answer:
Illustrated presentations of various cytological and histopathologic entities starts clicking Atlas here or on the banner on home page. It opens the contents of the Atlas with links to various topics.
Also, in the third strata of Cumulative survey there are links for various Atlas topics, located in the third column and marked by Y .
For example, if you click the underlined (marked) code 8723-00/X in the part of third stratum of Topography of Cytology coded 1964-02, you will get the illustrated presentation of a case, diagnosed by aspiration biopsy, of malignant melanoma metastatic in the inguinal lymph gland.
(Topography of Cytology, I stratum, click Lymph gland, click 1964-02, click 8723-00/X.)
This very case can be reached; also, clicking the underlined (marked) code 1964-02 starting from the part of third stratum of Morphology of Cytology coded 8723-00/X.
(Morphology of Cytology, I stratum, click Neoplasm, click 8723-00/X, click 1964-02.)
