{Reference Type}: Case Reports {Title}: Nodular and diffuse spindle cell infiltration in keloidal scleroderma: a case report. {Author}: Li Y;Zeng Y;Chen Z;Nie S;Wu Z; {Journal}: Front Med (Lausanne) {Volume}: 10 {Issue}: 0 {Year}: 2023 {Factor}: 5.058 {DOI}: 10.3389/fmed.2023.1291941 {Abstract}: Keloidal scleroderma is a variant of scleroderma that presents as firm keloidal nodules or plaques. Due to the similarity in morphology and pathology, it is often distinguished from a hypertrophic scar or keloid. We report a case of keloidal scleroderma with rare nodular and diffuse spindle cell infiltration in histopathology. Recognition of this unusual histopathological feature may help clinicians improve their knowledge and avoid misdiagnosis.
