- Abstract
This article describes the cytologic and histologic findings of a epidermoid cyst of the testis diagnosed by means of fine-needle aspiration (FNA) cytology. The gross and cytologic features are creamy aspirate, squamous cells, squamae, and fragments of granulomatous tissue. The cytologic features are fairly typical and similar to those observed in cutaneous epidermoid cysts; however, in this setting, the differential diagnosis should be carried out mainly with teratoma and dermoid cysts. The patient's age and precise location of the mass are paramount in the differential diagnosis. We believe that FNA is a reliable tool for the diagnosis of testicular epidermoid cysts, but the differential diagnosis with dermoid cysts should be based on histology., (Copyright 2004 Wiley-Liss, Inc.)

- Abstract
A study of the clinico-cytologic findings of 62 primary palpable lesions located in the scalp is reported. Trichilemmal cyst (16 cases) followed by lipoma (8 cases) and benign melanocytic proliferation (4 cases) were the most frequent benign conditions (n = 45); basal-cell carcinoma (6 cases) and squamous-cell carcinoma (5 cases) were the most frequently aspirated malignant tumors (n = 17). In the cytologic category of benign lesions (n = 45), cytohistologic correlation was carried out in 19 cases and the cytohistologic agreement was 100%, except for the three actinic keratosis cases that were diagnosed as atypical epidermal lesions. Cytohistologic agreement was 100% in the 16 malignant lesions in which excisional biopsy was performed. Based on the findings reported here, fine-needle aspiration is indicated as the first-choice technique for the clinical evaluation of primary scalp lesions. Experience with cutaneous cytopathology is essential in order to be able to carry out this task., (Copyright 2001 Wiley-Liss, Inc.)

- Abstract
Various types of superficial and deep-seated lesions may occur in the hand, causing concern to the patient and posing diagnostic dilemmas to the clinician. A study was undertaken to evaluate the utility of fine-needle aspiration (FNA) or scraping for the diagnosis of palpable lesions located in the hand. From a clinico-cytologic point of view, lesions were classified as superficial (n = 41) or deep-seated (n = 66), and aspirates were categorized into five groups: benign without specific cytohistologic diagnosis, benign with specific cytohistologic diagnosis, atypical, malignant without specific cytohistologic diagnosis, and malignant with specific cytohistologic diagnosis. Out of 107 cases with aspirates adequate for cytologic evaluation, 85 had histologic correlation; in 22 cases, histologic confirmation was deemed unnecessary because of unequivocal cytologic findings and/or clinical workup. Sensitivity was 90.9%, specificity 100%, and efficacy 98%. Based on these findings, we believe that FNA or scraping may help in the clinical workup of patients with either superficial or deep-seated lesions located in this anatomic region., (Copyright 2000 Wiley-Liss, Inc.)

- Abstract
This a retrospective study of 39 patients with pigmented cutaneous lesions with a subsequent histologic diagnosis of melanocytic neoplasia. The most important cytologic features seen in the fine-needle aspirates were assessed in the 26 cases deemed satisfactory for evaluation. Though cytology, along with essential clinical data, could enable a general diagnosis of melanocytic lesion and could differentiate it from other nonmelanocytic pigmented lesions, cytology could not provide a precise diagnosis of the different histologic types of benign melanocytic nevi, nor could it enable their differentiation from dysplastic melanocytic nevi or incipient malignant melanoma.

- Abstract
This is a retrospective reassessment of the most important cytopathologic features of 23 FNA smears with a cytologic diagnosis of panniculitis (PN). Patients were sent by clinicians. Clinical diagnoses were as follows: 16 suspicious of PN; three cutaneous metastases of an extracutaneous primary neoplasm; four with no clinical diagnosis. Thirteen cases were subsequently submitted to histopathologic study. The following cytoarchitectural patterns were found to be very useful for the cytologic diagnosis of PN: adipocytes intermingled with foamy histiocytes, donut-like granulomas, aggregates of adipocytes intermingled with plump histiocytes, a granular basophilic background forming a lattice-like pattern, and well-formed granulomas with or without multinucleated giant cells. Inflammatory cells could be seen combined with any of these cytoarchitectural patterns. FNA does not pretend to replace excisional biopsy as the diagnostic procedure for these entities but it is a very useful diagnostic tool in certain cases: for confirming the recurrence of PN previously diagnosed by histology, for evaluating the onset of subcutaneous nodules in patients with a non-cutaneous malignant primary neoplasm, for evaluating cutaneous nodules with no clinical suspicion, and for confirming a clinical diagnosis of PN and differentiating it from other entities that mimic PN clinically.

- Abstract
The smears of fine-needle aspirates corresponding to 137 histologically proven basal-cell carcinomas (BCCs) were reviewed. Satisfactory for evaluation were 127 smears; the remaining 10 were unsatisfactory. In 124 cases (97.6%), the cytologic diagnoses coincided with the histologic ones. The remaining 3 were false negatives, and the subsequent histologic correlation demonstrated superficial BCC missed by the needle. The cytologic criteria that permitted a diagnosis of BCC were: variable-sized and irregular-shaped cohesive epithelial clusters, round to oval monomorphic nuclei, bland chromatin pattern, and sparse cytoplasm. In 35 cases, a panel of antibodies was used in the smears and in the respective histologic sections. Epithelial clusters of BCC showed an intense and diffuse positivity for AE-3 and BerEP4, while UEAI and AE-1 were negative. Although HMB45 and S100-A tested negative in the epithelial clusters, a faint and sparse focal positivity for HMB45 and S-100A was seen in some clusters. This positivity is believed to correspond to just a few normal melanocytes and Langerhans cells trapped in the neoplastic epithelial clusters. In the histologic correlates, the same results were obtained, although HMB45 positivity was more conspicuous at the periphery of the neoplastic nests.

- Abstract
We have reassessed the fine-needle aspirates of ten cases previously diagnosed as granulomatous prostatitis (GP). Presence of unequivocal epithelioid granulomas (EG) or typical caseous necrosis was required for a smear to be diagnosed as nonspecific granulomatous prostatitis (NGP) or tuberculous prostatitis (TP), respectively. As a consequence only six cases met the criteria set up for the diagnosis of NGP and two for TP. The purpose of this revision was fourfold: to find out if there are other prostatic conditions which may be confused with GP cytologically, to investigate if there is a single cytologic finding that permits a confident diagnosis of GP, to find out if the etiology can be suggested on cytologic grounds alone, and, finally, to assess if carcinoma can be ruled out safely. We conclude the following: 1) There are various prostatic conditions which share some cytologic findings with GP; 2) the presence of distinct EG is the hallmark criterion of GP; 3) NGP and TP can be safely diagnosed cytologically but other forms of GP would require additional clinical data and ancillary techniques; and 4) carcinoma can be safely distinguished from GP cytologically. To succeed in this task the cytopathologist must diagnose carcinoma only if clear-cut carcinoma cells are present and must be aware of the reactive changes induced by the inflammatory infiltrate both in duct/acinar and metaplastic cells.

- Abstract
Although subacute granulomatous thyroiditis (SGT) is usually diagnose clinically, there are other thyroid conditions that must be ruled out. This task is achieved by means of fine-needle aspiration (FNA). In retrospect, the clinical and cytologic findings seen in 36 SGT cases are reassessed with a view to deciding which findings are most reliable for reaching a confident cytologic diagnosis. These are: the simultaneous presence in the same aspirate of the following cells: 1) follicular cells with intravacuolar granules and/or plump transformed follicular cells; 2) epithelioid granulomas; 3) multinucleated giant cells; 4) an acute and chronic inflammatory dirty background; 5) the absence of the following cells: fire-flare cells, hypertrophic follicular cells, oncocytic cells, and transformed lymphocytes. The absence of one or more of these requirements does not exclude SGT but does increase the number of thyroid conditions that come into the differential diagnosis. In these cases, it is essential to review clinical data carefully and to submit the patient to a close clinical and FNA follow-up.

- Abstract
This is a review of the fine-needle aspirates (FNAs) of nine pilomatrixomas (PMs) found in a series of 1,500 FNAs performed on skin nodules. The objective is to determine and list the cytologic findings that might mislead the less-experienced cytopathologist and to give him advice on how to avoid such errors. The following recommendations are made: 1) The FNAs should be carried out and the smears interpreted by the same person. 2) Clinical data, particularly age and location, are of paramount importance. 3) Shadow cells are pathognomonic of PMs. 4) Basaloid nuclei with prominent nucleoli should not be overdiagnosed. 5) Use both Papanicolaou and Diff-Quik stains. 6) Think of PM when performing and interpreting aspirations from subcutaneous growths located in the head and neck of young persons.
