Fine needle aspiration biopsy of mastitis secondary to empyema necessitatis. A report of two cases.

BACKGROUND: Empyema necessitatis is a relatively rare entity. Two instances of mastitis secondary to empyema necessitatis, diagnosed by fine needle aspiration biopsy are reported. CASES: One case was tuberculous in etiology and was initially recognized by cytologic findings of epithelioid and granulomatous cellular reactions and the presence of acid-fast bacilli, which were subsequently cultured and speciated as Mycobacterium tuberculosis. The other case was due to coexisting Actinomyces and Actinobacillus. These organisms were cytologically suggested by "sulfur" granules of filamentous, gram-positive bacilli, admixed gram-negative coccobacilli and Splendore-Hoeppli phenomenon in an exudative cell background and were confirmed by microbiologic culture as Actinomyces israelii and Astinomyces actinomycetemcomitans, respectively. CONCLUSION: The usefulness of fine needle aspiration cytology in the diagnosis of empyema necessitatis, supported by ancillary microbial culture, histochemistry, and radiographic imaging, is well illustrated by these two cases.

Alternative method of hemorrhage control in full strength formocresol pulpotomy.

PURPOSE: This investigation evaluated the success of a formocresol pulpotomy technique in which hemostasis was obtained with the same formocresol dampened cotton pellet used to medicate the root pulp stumps and to compare the findings of this investigation with data of published formocresol pulpotomy studies in which hemorrhage was controlled by traditional means. METHODS: Clinical and radiographic data were available for 194 primary molars in 112 patients with follow up times ranging from 5 to 109 months (mean = 38 months). RESULTS: Overall radiographic success was 87%. The most frequently observed pulpal responses were calcific metamorphosis (34%) and internal resorption (10%). Overall clinical success was 98%. Only 7 of 194 molars were extracted due to radiographic and/or clinical failure. Overall cumulative probability of survival remained high over time with a cumulative survival rate of over 94% over 4 years. CONCLUSIONS: The success rates for this variation of the formocresol technique are comparable to those success rates in the literature where hemostasis was obtained in a separate step using a nonmedicated cotton pellet. The results of this study suggest that using the same cotton pellet dampened with full strength formocresol to obtain hemorrhage control and medicate the root pulp is an acceptable variation of the traditional formocresol pulpotomy technique.
