Herpes zoster as a cause of atypical chronic ulcerations associated with tofacitinib.

Tofacitinib is a targeted inhibitor of janus kinase (JAK), currently approved for the treatment of rheumatoid arthritis. We present a patient on treatment withtofacitinib who had an episode of classic dermatomal herpes zoster followed months later by atypical chronic cutaneous ulcers also caused by herpes zoster.

'Atypical' and 'suspicious' diagnoses in breast aspiration cytology.

Background: In 1996, the National Cancer Institute (NCI) recommended five categories for the diagnosis of breast aspiration cytology: benign, atypical, suspicious, malignant, and unsatisfactory. The authors evaluated the usefulness of separating inconclusive diagnoses into the aforementioned atypical and suspicious categories. The current study examined the correlation between cytologic and histologic findings made in breast aspiration cytology specimens that were categorized in accordance with these NCI guidelines.

Experience with an automated microwave-assisted rapid tissue processing method: validation of histologic quality and impact on the timeliness of diagnostic surgical pathology.

We studied the effect of a fully automated microwave-assisted rapid tissue processor (RTP) on histologic examination and on the turnaround time for surgical pathology reports. A quality assurance program reviewed the histologic sections obtained by the rapid processing method for the last 3 calendar years. In addition, the histologic results from this method were compared blindly with those obtained from the conventional overnight tissue processing (CTP) method by 9 pathologists with different levels of experience.
