Deep Herpes.

Herpes viruses are known for infecting epithelial cells and manifesting as vesicles. However, herpes viruses can also infect stromal cells. While established in the ocular setting, cutaneous stromal herpes (deep herpes) is previously unreported and may evade clinical and microscopic detection.

Fine-needle aspiration of primary Langerhans cell histiocytosis of the thyroid gland, a potential mimic of papillary thyroid carcinoma.

The clinical presentation of Langerhans cell histiocytosis (LCH) as a primary solitary nodule in the thyroid gland is rare. As a result, there are few reports of its cytologic features in thyroid aspirates where it can pose a diagnostic pitfall. CASE AND CONCLUSION: To foster familiarity with its cytomorphology, we report the fine-needle aspiration biopsy (FNAB) findings of 3 specimens from 2 patients with LCH presenting as a solitary thyroid nodule.

Measuring the clinical impact of pathologist reviews of blood and body fluid smears.

Context: Despite the widespread practice of pathologist review of blood and body fluid smears, little is known about its impact on improving patient care.

Objective: To assess the clinical usefulness of pathologist review of blood and body fluid smears.

Design: Survey study.
