Sir,
A 39-year-old female presented with a localized enlarging indurative purpura on the right lower leg that had developed within a month [Figure 1]a. She had been taking ibuprofen, propionic acid nonsteroidal anti-inflammatory drugs (NSAIDs), twice a week to treat her headache. Histopathologically, the lesion showed neutrophilic exocytosis with intraepidermal micropustules and leukocytoclastic vasculitis (LCV) around the postcapillary venules [Figure 1]b and [Figure 1]c. After this first episode, she discontinued ibuprofen, and the lesion resolved within a week. | Figure 1: Clinicopathological findings at the initial visit. (a) Clinical appearance. Indurative purpura on the anterior side of the right lower leg. (b) Histopathological findings of the first episode, Hematoxylin and eosin staining (40 ×). Intraepidermal abscess and perivascular inflammatory cell infiltration with erythrocyte extravasation. (c) High power magnification (Hematoxylin and eosin staining). Neutrophilic exocytosis with intraepidermal micropustule formation and perivascular neutrophilic infiltration with erythrocyte extravasation and nuclear dusts was observed

Eight months later, she again presented with a recurrence of eruption on the same area [Figure 2]a. The lesions were painful, indurative purpura with erosion, pustules, and subtle postpustular desquamation [Figure 2]b. Just before the second episode, she had been taking loxoprofen, a propionic acid NSAID, as an abortive medication. Furthermore, she continued it even after the recurrence of eruption to alleviate the pain of the lesion. Meanwhile, the new lesions developed and spread. They appeared a few hours after she took loxoprofen, starting as nonfollicular pustules with erythema, and eventually merged to form pustular purpuric plaque. Histopathologically, the lesion showed the same features with the initial biopsy specimen but was more extensive [Figure 2]c and [Figure 2]d. After discontinuation of loxoprofen, the lesions subsided immediately with residual pigmentation [Figure 2]e. The lymphocyte-transforming test (LTT) performed before the withdrawal of loxoprofen was positive for loxoprofen (stimulation index: 253%), but negative for ibuprofen (stimulation index: 127%). The use of propionic acid NSAIDs was prohibited, and now 3 years have passed without recurrence. | Figure 2: Clinicopathological findings at the time of recurrence. (a) Clinical appearance. Pustular purpuric plaque on the anterior side of the right lower leg. (b) Clinical appearance. Some pustules were nonfollicular pustules with subtle postpustular desquamation (arrowhead). (c) Histopathological findings at the time of the second episode. Hematoxylin and eosin staining (4 ×). An intraepidermal abscess and perivascular inflammatory cell infiltration were observed. (d) High power magnification (Hematoxylin and eosin staining). Neutrophilic exocytosis with intraepidermal micropustule formation and perivascular neutrophilic infiltration with nuclear dust and erythrocyte extravasation around the postcapillary venules. (e) Clinical appearance of the right lower leg 7 days after cessation of loxoprofen. Lesion subsided with residual pigmentation

The clinical findings of nonfollicular pustules, postpustular desquamation, and the histopathological findings of intraepidermal pustules and perivascular infiltration of neutrophils in this case met the diagnostic criteria for acute generalized exanthematous pustulosis (AGEP).[1] Together with the clinical course that the eruption appeared only on the right lower leg immediately after drug administration, we are speculating that this case comprised characteristics of acute localized exanthematous pustulosis (ALEP).
ALEP is an extremely rare form of AGEP, which is characterized as multiple pustules in localized areas associated with the drug.[2] Currently, 26 cases have been reported. It typically occurs on the head and neck areas, but it can also occur on the extremities. Reported causative drugs are ibuprofen, docetaxel, antibiotics including amoxicillin and clindamycin.[3],[4] In this case, two different NSAIDs induced the lesion. While LTT was negative for ibuprofen, we are speculating that its structural components played some role to cause the lesion as both loxoprofen and ibuprofen are propionic acid NSAIDs sharing similar chemical structures.
The present case also comprised the feature of LCV, which reflects the purpura on its clinical appearance. To the best of our knowledge, no cases of ALEP with LCV have been reported in the past literature. However, as cases of AGEP with LCV have been reported,[1],[5] it is possible that ALEP can accompany LCV depending on the interaction between the drug and the administered patients.
In conclusion, the possibility of ALEP accompanied with LCV and association of medications should be considered when we see the localized pustular purpuric eruption taking the acute clinical course.
