Subcutaneous Granuloma pyogenicum in Patients with Antiphospholipid Antibodies

Superficial (nodular) thrombophlebitis as a heterogeneous entity with distinctive clinico-pathological aspects: Correlation with the underlying conditions

BACKGROUND

Superficial (nodular) thrombophlebitis, referring to a thrombo-inflammatory disorder of dermal-subcutaneous veins, encompass a spectrum of nodular lesions often associated with inflammatory, infectious, neoplastic or thrombophilic diseases.

OBJECTIVE

We postulate that distinct clinico-pathological features may correlate with the underlying conditions.

METHODS

We conducted a retrospective monocentric study of all patients seen in our dermatology department for a superficial thrombophlebitis, completed with a literature review. Clinical and pathological data were extracted from the patient files and articles.

RESULTS

A total of 108 cases of superficial thrombophlebitis was analysed. Forty-five percent manifested as elongated nodules clearly evoking vascular involvement, while the other 55% were presenting as nodules or plaques. The elongated phenotype was strongly associated with malignancy or thrombophilia if a pure thrombosis was demonstrated histopathologically, while tuberculosis was the main underlying condition if a granulomatous vasculitis was present. Panniculitis-like lesions were mainly corresponding to erythema-nodosum-like lesions of Behçet's disease, characterized by the distinctive feature of thrombotic veins with an associated leukocytoclastic vasculitis.

LIMITATIONS

Retrospective design and risk of publication bias.

CONCLUSION

Superficial (nodular) thrombophlebitis is a heterogeneous entity with a distinct clinico-pathological presentation that strongly points to the nature of the underlying medical condition, thus guiding the medical workup.

Pyogenic granuloma presenting as an orbital mass

Pyogenic granuloma (PG) of the eyelid and orbit is typically associated with trauma or surgery. We report a rare case of an orbital intraconal PG arising de novo in association with an orbital artery.

Lobular capillary hemangioma in the soft tissue of the finger: sonographic findings

OBJECTIVE

The purpose of this study was to describe the sonographic findings of pathologically confirmed subcutaneous lobular capillary hemangioma of the finger in six patients.

MATERIALS AND METHODS

The clinical records were reviewed for data, including the patients' age and gender, the clinical presentation, a history of trauma, and the tumor site. The sonographic findings were retrospectively analyzed for the specific location within the superficial tissue, the tumor's size, shape, and margin, the internal echogenicity, the internal echo texture, the presence of calcification, the presence of a hypoechoic rim, and the internal vascularity.

RESULTS

The study group consisted of three men and three women, and the six patients' mean age was 39 years (age range: 13-67 years). All the patients were admitted with a painful nodule or a painless protruding nodule in the finger with easy bleeding on contact. In all cases, there was no history of trauma. The mean size of the tumors was 0.85 cm. All the tumors were ill-defined, oval, subcutaneous nodules without calcifications or any hypoechoic rim. Color Doppler sonography showed marked internal vascularity in both the central and peripheral tumor regions in three cases and scanty vascularity in the peripheral region in three cases.

CONCLUSIONS

Subcutaneous lobular capillary hemangioma should be considered when an ill-defined, oval, vascular subcutaneous nodule without calcifications or a hypoechoic rim is seen in the soft tissue of the finger, especially if this tumor is a painful small nodule or a painless protruding small nodule with easy bleeding on contact.

A Case of Lobular Capillary Hemangioma (Pyogenic Granuloma), Localized to the Subcutaneous Tissue, and a Review of the Literature

Lobular capillary hemangioma (pyogenic granuloma) is a common vascular proliferation that typically occurs in the superficial dermis, although rarely a subcutaneous form has been reported. Although these lesions are considered benign, localized recurrence after excision and satellite spread of the lesions are known phenomena. A case of lobular capillary hemangioma with the unusual features of both subcutaneous localization and locally aggressive behavior following surgery in a patient with a history of estrogen use and local trauma prior to the onset of the lesion is presented. The literature of lobular capillary hemangioma is reviewed, and the differential diagnosis is discussed.

Clinicopathological and Ultrastructural Study of Multiple Lobular Capillary Hemangioma after Scalding

We herein report 2 cases of multiple lobular capillary hemangiomas after scalding. The patients exhibited papules and nodules on the scalded areas after healing. Histopathological examination of the lesions showed capillary proliferation in the upper dermis with edematous stroma containing inflammatory infiltrates predominantly composed of neutrophils. Biopsy tissue and secretion specimens from lesions of case 1 were cultured for bacteria, and both grew Enterobacter cloacae. Ultrastructural examination revealed features typical of a lobular capillary hemangioma and viral inclusion bodies in the epidermis of case 1. Multiple lobular capillary hemangiomas after scalding are rarely reported. Trauma may play an important role in the development of this rare condition. Accumulation of similar cases and its precise observation is needed to confirm the associations and to establish an etiological link between the disease and the pathogens.
