ABSTRACT: Crystalglobulinemia (CG) is a rare disorder characterized by crystallization of monoclonal immunoglobulins in the microcirculation leading to multiorgan vascular thrombosis and ischemic injury. The main cause of CG is multiple myeloma. We report a case of a 52-year-old man who presented with widespread necrotizing plaques and ulcerations. A skin biopsy revealed eosinophilic rectangular-shaped crystals occluding the lumina of blood vessels with no associated features of vasculitis. The crystals were Periodic acid-Schiff stain positive. The findings were diagnostic of CG. Extensive work up lead to the discovery of multiple myeloma. Awareness of CG is important because it may be the first presenting manifestation of an underlying serious hematological malignancy.

A 77-year-old female patient presented with bilateral tender, swollen, erythematous, focally crusted cheeks with a discharge of pus and necrotic material, which had developed one month after autologous fat transfer and a corrective injection procedure conducted to correct an overdone fat transfer. Histopathological examination of the discharged material using routine hematoxylin and eosin staining revealed degenerated collagen admixed with three different filler materials. Scattered all throughout the specimen were numerous thick-walled, basophilic, nonbudding spherical bodies of variable sizes. The bodies stained positively with Periodic acid-Schiff and Alcian blue and showed internal septation and sporangia with a morula-like appearance. The morphology of these bodies was characteristic of a infection. The patient was treated by surgical drainage accompanied by itraconazole 200mg daily for six months, ultimately showing marked improvement.

Abstract

BACKGROUND: The distinction of trichoepithelioma from basal cell carcinoma in small superficial biopsies is important but often challenging. This has inspired many scientists to test the validity of immunohistochemical markers in the differential diagnosis.

OBJECTIVES: To develop an immunohistochemical protocol that helps in differentiation between both trichoepithelioma (TE) and basal cell carcinoma (BCC) with higher sensitivity and specificity.

METHODS: Using standard immunohistochemical techniques, we examined 10 TEs and 19 BCCs for the expression of CK19, Ki-67, androgen receptors (AR), CD10, and PHLDA1.

RESULTS: Immunoreactivity of AR, Ki-67, and CD10 in tumor cells was significantly higher in BCC than TE with a diagnostic accuracy in BCC of 75.5%, 75.8%, and 79.3% respectively, whereas immunoreactivity of PHLDA1 in tumor cells and stromal CD10 was significantly higher in TE than BCC with a diagnostic accuracy in TE of 100% and 82.8%, respectively. In contrast, immunoreactivity for CK19 showed no statistically significant differences between both tumors.

CONCLUSION: The analysis of CD10, Ki-67, and PHLDA1 can be used as a helpful immunohistochemical panel in the distinction between TE and BCC especially in small and superficial biopsies.
